When setting the mechanical cam timing remember that when all timing marks are lined up that the cam dowel pins are in the 12 o clock posistion.

When you replaced the timing belt were all the timing marks lined up correctly?Since it stated makeing this noise have you pulled the timing belt cover to ensure all of the timing marks still line up?

Many builders use the various thicknesses of head gaskets available to set the quench clearance.For example Deck height (+ or-) piston height depending on whether the piston sits above or below the deck while at TDC and by how much. If the piston is .010 below the deck when at TDC and one...

In the end it boils down to personal preference and the owner’s budget. I have used plenty of aluminum and titanium rods for past builds but none were in a 4G63 platform, therefore I can not comment on their specific use in such.I do not mean to harp on the budget question; I am well aware...

No most likely not but as you brought it up I could not resist, sorry

Everything streches when rotated fast enough with enough weight on the end of it. If this was not the case no one would need to leave .080 for piston to valve clearance, ar .040 for deck clearance.We are not talking about perminent strech here, only dynamic. Some combonations may need some...

So is it safe to say that your looking for a budget build / bang of the buck build that will rev to 9000 rpm, make 600 plus HP, and have the life expectency of a street build?

A good starting point would be to establish a budget for your built. Doing so may allow to to pass over some rods, or if price is a concern not bother with high end options.I have used five differnt types of rods in various DSM builds over the years. 1: Oliver great rod, super tough, but...

Based on the second to last picture with the "F" on the cam I would guess stock cams, or possibly regrinds. The "F" is a factory grind designation and have seen "A, B, C, D, and F" cast into many 4G63 cams over the yaers.Aftermarket cam manufacturers typically do not cast identifiers into...

No differences in the output of the oil pumps, the only real difference is in the casting on the 95 and up 7-bolt motots to allow mounting and use of a crank angle sensor. As someone else posted just use the standard 6-bolt pump and one of the three differnt 1G cam angle sensors. I have found...

How far it it recessed on the front side? Generally speaking and if perfection is the objective they are usually centered.

Yuo should be fine either way, I most always use the compressed air method, unless compressed air is not available.

Nothing wrong with doing it yourself if your careful.Start with 400 grit and then go finer to 600. Clean it well when done, including oil passages.

With a good tune and proper boost control you should be fine.I have a 1G with 9.0:1 Wiseco's that currently has 46,257 miles on it, with no troubles.

So do you have everything sorted out now?

In a nut shell you get what you pay for.Depending on your goals/expectations you may want to choose higher quality components.I have used Top Line parts for some budget builds in the past with good results. I have never had a motor fail simply because of poor quaility components, there...

"Yes it is always best to assume that the manufacturer had a quality problem":pray:Continue on with ignoring the real issues at hand and the problems will also continue.The picture provided shows the back of the ring land quite well, and one can see that the depth is stepped deeper...

I have seen this before it is from incorrectly gapped piston rings. In a nut shell the piston ring end gap was too tight, and the thermal expansion of the rings caused the pistons to deform.This is an assembly problem.

Most piston rings are either cast or ductial iron as their main material, many have a thin plasma-moly, or chrome facing on the top ring.Generally speaking chrome faced rings seat better with a slightly rougher cylinder wall finish due to the hardness of chrome. Moly or plasma-moly rings...

Did you measure these with the main caps, bearings installed and torqued? If not your numbers as mentioned are off. This is because the torqueing process stretches bolts/studs firmly beds main caps into thier respective block registers, and apples a known amount of crush to the bearings.If a...

I have four on mine too.Another good tip would be to install all the bolts and thread them all the way in by hand, then install and tension the belt, and then go back and tighten the pulley bolts.

First check the packaging, for any/all information regarding instalation. It is not uncommon for less expensive ring sets to come ukmarked.Most will have a legend that denotes the cross sectional shapes of various rings, and through text or arrows indicate the direction of instalation...

Yes you will need to remove the valves in order to have the head surfaced.Well unless the valves are sunk so far into the seats that they are far enough below the deck surface, but then you should be thinking about replacing the head.It would be a good idea to have the head surfaced...

I was thinking perhaps the piston slap issue should be addressed as well.Since the connecting rod spends most of its time at an angle to the crank pin axis there are what is called major and minor thrusts. A major thrust is the downward movement piston's force against the cylinder wall...

The reason for the off set wrist pins is to reduce the shock loads to the piston and the reciprocating portion of the connecting rod. Off setting the wrist pin causes the piston to reach TDC at a slightly diffenrt time than the recipercating part of the connecting rod, effectivly speading the...

The "050" refers to the piston's oversize using the metric system, this translates to 0.020 oversize in the SEA system.

Without seeing a picture, I would have to agree that the pistons (slugs) are in backwards. If Manely uses an on center wrist pin (gudgeon pin) then there may not be a mark on the piston indicating forward.It would have to be off in whole tooth increments, head surfacing and decking can make...

ENGINE MACHINE WORK EXPLAINED (part 1)Purpose: I have noticed that many DSM tuners out there are attempting your own engine rebuilds, and many have questions on what machine work to do, how the various types of machining processes differ, and the capabilities of the various machines. This...

Something tells me you may need a little more work & parts.1: your #1 rod that spun the bearing is most likely junk, even if you could have it reconed back to size the heat treat is gone, so forget about it and replace it. Verify that the other connecting rods did not get too hot, this...

You may just be hearing the valves shut in the cylinders not being tested since you have the spark plugs out. They are metal and so are the seats they seal on.

Case hardening generally penetrates about 1.5mm or 0.059 inches per side. I opened the slot about .018 or 0.009 per side, this made the final width of the slot consistaint with the plethora of old stock intake cams laying around the shop.I did end up contacting Crane, and they did offer to...

Is the quoted piston weight with or with out the wrist pin?

This is regarding Crane Cams Mitsubishi 4G63 camshaft set P/N 435-0014 grind number MIT-264-25R-10 Intake duration 256 lift .443 Exhaust duration 245 lift .424Has anyone run into a problem with the intake cam, where the slot cut into the back of the cam for the CAS (cam angle sensor) is...

warming your car up will not increase the compression numbers from 10 to 130+.Seeing 25 psi or less is not unusual, the cranking compression psi value is dependent on many things. You burnt or bent something.Since you saw 0 psi last year, and this year you see 10 psi, just means you did...

Another quick question If you did not have the block and head surfaces milled, how did you clean and/or prepare them for the new head gasket replacement?

Sorry for the stupidity related questions, but I had to ask.I have never seen a head gasket leak after installing but before running, and have it be fine later, but I am not going to claim to have seen everything either.The top and bottom layers of the Cometic head gasket are very thin...

Well since I wrote my responce this morning, I have some concerns that it may not have sat overnight yet, or are you talking about what you have done so far?In re-reading your original post I see you did this at least a month and a half ago. Is it still true that you have not yet fired up...

This will be hard to explain in text but I will try.The Cometic and other MLS type head gaskets by nature have some compressibility. I.E. they will continue to compress after the torqueing process. This can be best shown by the following example.I will use your stated torque values of...

Lets all remember that we are dealing with a four stroke engine here. 720 degrees of rotation for the crankshaft per complete cycle, and 360 degrees for the camshafts. Therefore if the cams are 180 degrees out and number one piston is still at TDC the timing is still fine.The piston passes...

If you follow the paper work that comes with the Cometic head gasket they reccomend to install the head gasket dry, and also reccomend a surface finish of 50 or better. Additional checks include ensuring that none of the rivets that hold the three layers of the Cometic head gasket together...

Well first lets all try to remember some of the basic rules of physics. 1: Airflow ( in this case) will follow the path of least resistance 2: Curves or turns should be kept to less than 20 degrees. 3: The ideal gas law is PV=nRT Where P= absolute pressure V= the volume of the vessel n=...

If you do not end up with the original main caps from the block, then you are more likely to need align boring than align honing. This is because the main housing bore halves (upper in block & lower in the main cap) are aligned by the main cap register I.E. the machined verticle portion on the...

Well there are several possibilites: Many oil pumps may look good or ok, but if one was to measure one, it will most likely tell a differnt story.According to Mr. Haynes the 2.0L oil pump tollerances are as follows. Tip clearance Drive gear 0.0063 to 0.0083 limit 0.0098 riven gear 0.0051...

The upper main bearing halves, have grooves to promote oiling into the crankshaft main journal oil holes to subsequently provide lubrication to the connecting rod bearings. Fully grooved main bearings allow this to happen for 360 degrees of crankshaft rotation. However since the stock Mitsubishi...

Having used both several times. I prefer Scats. I have noticed many times that the Eagle rods have a parrallel problem between the axis of the crank pin bore and the wrist pin bore. People most likely do not check this.For my presonal motors I have always used Olivers.

First off, a correction to my last post. "It should state .020 over not .030 for a finished bore diameter of 3.366" sorry.You should take the block to a qualified machine shop and have the bores measured to verify their doameter, and oversize if there is one. Or you could do it yourself if...

88mm = a 3.465 inch bore diameter, but as stated above this is the spec for the 2.4 liter block, not the 2.0 block.

Like "Purevil" stated are you sure the it is .050 over or 3.396 diameter bore. Or do the pistons say .5 in which case it is .030 over or a 3.366 diameter bore.

Are you looking for 1G or 2G parts?I don't know of any place still selling new 1G hangers.Spartan Auto in Lansing Michigan was the last place I found 2G hangers.
