little help...no compression, warped valves, please read!

[the heeat]

Ill give the short version...fuel filter clogged because of gas tank so i replaced tank, filter and pump, then flushed all lines and cleaned injectors. Car jumped time due to a garage not tightening a tensioner pulley when they changed water pump for me...now the garage (this guy's Done work on my buddys dsm) its at told me when he put it back in time, from being 4 teeth off, it jumped two after he fixed it...he did compression test and two cyl were at zero and when he looked inside, some valves were warped. He's going to fix it for me, but i want to know what Options i have for mods/improvements in this area while he has it apart....this is my dd/playtoy, not a drag car or race car, but i still want to know what things i can do that aren't overly expensive twill still give me a little more hp. Thanks.

Well rebuild what you have and invest in other areas of the car because the stock is plenty good for a dd and in most cases even a drag car with proper mods.

Is he able or have the know how on how to port and polish? You can clean up the intake and exhaust ports. If he can't do it, can you have him send it out to someone that can? You can install some cams. Maybe like 264/264's for a little more bump. Do you have any plans for the car? You can set the head up for future mods. It doesn't hurt to put in a stronger and/or lighter set of springs, valves, and retainers. Other than a port and polish or bigger cams that will compliment a bigger turbo, there's not much you can do. What's your budget?

If this guy cant set tension on a tbelt I damn sure would want him to do any cylinder heads mods.

 

[gieri002]

Maybe some new springs/retainers and cams? ARP head studs? A new headgasket of your choice? I'm with these guys though, I wouldn't let that guy touch my car.

The guy working on it now didn't do the water pump, which is what set all this mess in motion...guy now is cleaning up other guys mess. I'm completely illiterate when it comes to the internals of a motor...i kind of know, but at the same time i don't.

I footy know if he knows how to p&p, I'm guessing he does from all I've been told about him but i would have to ask...and i don't know what you mean by cleaning up the Ports? I don't know about cams, head studs, new head of my choice (?), lighter springs, setting up the heads, etc....as for my plans, ill get a bigger turbo at some point, an mbc, fpr, MAYBE bigger injectors, MAYBE a fmic, but as for the internal engine i don't have many if any plans unless completely necessary.

That's "don't" not footy......sorry bout the auto correct guys

If you're planning on putting a bigger turbo in the car, then you're also going to want to look into new injectors and some type of tuning solution, because larger turbo on stock tune and injectors=fuel cut.
As far as porting, Jafromobile has a few good videos on youtube that would give you an idea of what they're talking about with "cleaning up" the head ports.

But all in all I'm with the rest of them, just get an upgraded set of springs/retainer, 3g lash adjusters, and a pair of street friendly cams, I wouldn't really worry about upgrading valves ATM with what you listed as your build plan.

Update: just got off phone with my mechanic and he said he "thinks" there's might be a broken valve..not 100 yet, he's gonna investigate more this eve and this weekend. He said if so, i would need a new head...suggestions? ...info? ...u guys got any heads for sale? If and when i do get a bigger turbo, i would probably just get a 16 because i don't want to have to change alot if its not necessary.

Sounds on the sketchy side.

If you snapped a valve, with the valve head banging around in the cylinder, it would knock and the spark plug would be mangled.

Also fishy is saying warped valves with the head installed.

Even if you did drop a valve the head can be fixed if needed, but it would be more cost effective to get a good rebuilt head from a Supporting vendor or Supporting freelancer that build the heads all the times.

Also with a dropped valve, you would need a new piston, it is not the little dings you get with bent valves.

Sounds like he may be trying to get you to pay for something he screwed up.

Could be when the belt jumped 4 teeth then 2 after the belt reset that some of the valves got bent.

All he's told me is from him doing little things...were gonna tear into it this weekend so I'll know for sure then. I trust him and his word from all the work he's done for me and my friends in the past. I didn't check anything other than fuel system from injectors to tank and cleaned/replaced what needed, never checked anything else. He's been giving me an idea of what's wrong as he can check it out...he just told me that i may need a new one, so over just been checking things out.

...a new head gasket of my choice? I don't understand what a new/dif headgasket of my choice would matter.

It's dead. Parting out....it's in the classified, so check it out if ya need anything. Thanks.
