So I took my head to the machine shop and they said it needed 4 intake valves and to have the head milled and that was it. I previously tested the compression in cylinder #4 and it came up as 0. There were actually some small metal shavings in the oil pan but I couldn't see any scaring on the pistons or cylinder walls when I pulled the oil pan. Should I get the bottem end looked at also? Or just get the valves done and put it back together? I don't really have the money to get the bottom end looked at but could do it if needed but I'm trying to save as much as I can toward my turbo setup.
 
I was in the same boat. Found aluminum shavings in my oil pan. Mine was the rear balance shaft bearing. Find out where the shavings came from before you reassemble the engine.
 
FTW!! Any debis in the motor is the deviil.

Post 5 and 6 are dead on!! If you don't pull, breakdown and clean the metal shavings will damage your new head your old turbo,and anything else where oil flows. Better safe now than sorry later been there and done that. Just my $.02:cool:
 
Ya you all are right I shouldn't try to jeopardize my new head and everything else. I just wanted to save money. There were a small amount of gold shavings in the oil pan when I took it off. I am getting the head machine and 4 valves replaced right now. I guess I'll take teh short block over there too and get them to take a look at it and make sure everything is alright.
 
Dropped everything off at the machine shop and just waiting on a call about the shortblock.
I found out the head had 8 bent intake valves so I am replacing those. Here is the machine work I've been charged for so far, does this sound alright? I'm not that familiar with prices for machining.

Head teardown/clean/inspect $60
Valve Job $135
Shortblock Teardown/Inspect/Clean $200
 
are they changing the valve guides, the ones with the bent valves?

I would bet that the head has cracked guides.

also HOW are they going to surface the head?
Do not let them belt surface it!!
http://www.dsmtuners.com/forums/cyl...0613-why-not-let-your-head-belt-surfaced.html

the surface needs to look like this, MLS or composite.

make sure they also test the valve springs, most are wore out by now....

and spring info...

also have them measure head thickness, new spec is 5.200 for every .007 milled off the head closes the combustion chamber by 1cc

also before you install the head you may want to do this oil mod...

From what I was told they said for me to just bring in 8 intake valves and valve stems so I'll have to ask about the valve guides.

Also, on the head they said it will need to be milled, which is the same as surfaced, correct? I'll have to make sure they don't do that then.

I do actually have a MLS headgasket so I'll def. need to find out about that.

With the oil mod do I still need to do that if I plan to go with an HX40 is that still necessary? From what I read you had to put an oil restrictor on, right?
 
if you run an MLS HG then the surface on the head and block is very important.

yes, mill and surface are the same thing.

will you be feeding the turbo from the side of the head or from the OFH?

you should do the mod anyways to make sure you get the proper flow of oil to the cams and HLAs

I'll have to call the machine shop and def. check on the surface the block is milled with then. I'll do that tom. ASAP.

I'm not sure how I will be feeding the turbo. Which one is better? I'm kinda new to DSM's really but have had one before but only bolt-ons.
