DOHC headwork

[goatman]

OK, so my car was leaking a shit load of oil, like a quart in a day, and I was told that maybe valve guides or seals were the problem. So, I put the car in the garage and started tearing it down. I got down to the heads, with the lower intake manifold off, and found that all the bolts in the oil distribution block were loose. Two were only finger tight, and the others required only a quarter turn of the ratshit to loosen them up. So thats where the oil was going. Now for my question: Since I've already got the motor tore down this far, what are some good mods to do on the heads/cams/intakes etc? Any input would be greatly appreciated.

Not much you can do really unless you want to dive into custom work. Although P&P heads never hurt no one

You can go with lighter lifters, and ported heads and intakes. Thats really the best upgrades for having it torn down how you have it if you want to have anything done at the moment.

Yea, I was thinking of getting the heads ported and polished, where can i get the lighter lifters?

Coincidently form Sappyse107, the guy that posted right above your last post and below my 1st post

They look to be nice, but havn't(IIRC) been tested yet. I guess they got them on a car and it ran fine, but I don't remember anything on if they helped or not.

oh, yea, it kind of pissed me off when the car started leaking all that oil. I bought it in march, with 77,000 miles on it, a one owner car, but someones done something to it before, i found a socket jammed onto one of the LIM bolts, a 3/8", so someone who didn't know they were 10mm

Im running them now and so is pocket-rocket. He has lifter tick for some reason though and I have none at all. As for a difference, well I dunno cause I ported my heads out more at the same time and put an underdrive pulley on. I know they work, but I can't tell you just how much they do for you. Lighter valvetrain is always a good thing though, especially for high RPM.

If you want headwork done, I do that and have done several different variations on my car and a friends so I know what works, what doesn't work so well for low end, and what works very well (but is a lot more work). You can also have a machine shop do it, just make sure they know what they are doing with this motor and not just porting it out like mad. One of these days ill have my store up and running with pics and more details:P

also you can try the ex 13* cam mod it is almost free.(u have to get a cam tool made or make it yourself)

OH, AND ALSO WHILE YOU HAVE THE HEADS OFF REPLACE THE DISTRIBUTOR O-RING AND MAYBE YOUR TIMING BELT/IDLER PULLIES IF THEY HAVEN'T BEEN DONE YET.

What oil are you running and what oil is he running?

[SappySE107]

im running 10W30 advance brand at the moment and I think he was running 5w30 mobil 1. Ill be running that oil in the next few days so I will know for sure then.

How many miles do you each have? Becuz at 127k on my old motor with Mobil 1 5w30, the lifters were still noisy as shit. But now, still with Mobil 1, they are silent.

[SappySE107]

He has over 100k, and I have about 37k. Our lifters however are the same age basically, though I probably have more miles on mine since I have been driving around a hell of a lot lately. I think he switched to 10W30 and they got quieter but he still has noise. I had noise when I was 1.5 quarts low but I added oil as soon as I started it up and heard them getting pissed.

That would probly explain it even though the lifters are the same age.

[SappySE107]

I ran his lifters in my car when I first got them and they did sound different. They didnt tick at all and sounded pretty sweet. I think they just don't like being in a lumina:P His engine is in great shape though. Its the only stock chip that I have seen be dead on for the fuel tables.

That is weird. Maybe I should get the motor in a Fiero before I talk business with you....
