1G I think something bad happened...

[Zultane]

So, I'll make long story short. I randomly got a bad noise in the engine bay today.

After much time, I took off the valve cover... looking at the engine, the far left rocker, on the closest side to the firewall, had came off. Intake cam.

I took off the pieces that holds down the cam. Again, I don't know their name, but I know their function. Well, on 2 of those, they are chewed up, gouged, and whatever other word you want. They are BAD. on the cam, same thing, they are really chewed up.

I didn't take apart the exhaust side, but, visually, everything looked ok. I suspect this would be what was causing my terrible idle, that I haven't been able to tune out.

I was forced to leave the car at my parents who I was visiting. I'll have to go back out there this weekend.

Somebody bear me the bad news, what am I looking forward to? Bent valve(s)? Clearly need new cams, which means springs as well. May as well take the head off and inspect the innards?

Or am I better off buying a new 6-bolt and keeping mine for parts?

agreed, full drag car I would choose kelfords since they are more aggressive. I went with bc 272 on my rebuild mainly so I didn't have to fully upgrade the rest of the head. But I also daily drove mine

Store the running 6bolt numbers matching block in a very safe place. This is a dsm, a running engine is a big deal.

Find a spare, preferebly virgin, 6 bolt and have that rebuilt. I know stock pistons/rods can hold 500+ and one is even in the 9's. Forged is overkill iIf you arent making big power imo. Like others have said stroker cranks are often questionable. Stock cranks are forged and kick ass, find a nice one and have it polished, avoid cranks that are chewd up and need to be cut. For forged pistons and rods just do your research and find a good machine shop that knows DSMs.

Parts wise I have had good luck supertech valve springs and kelford cams. Kelfords are by far the best on the market butI alsp really like the delta dks 272 regrinds in my talon. They were cheap too.
I wouldn't look into oversized valves or porting for your goals. Once again a reputable machine shop can rebuild it for you. This should include hot tankin valve job, resurfacing, at a minimum.

These videos will help you a lot

Im putting together my shopping list on extreme psi right now. Got some kelford cams, and springs.

Question. Im looking at valves, and they show (STD) standard obviously, (+.5) and (+1.0)

What exactly is this saying?

 

[Xit40]

STD, +.5 and 1 are the valve sizes in mm.

I need some help real quick. Im about to take the head off right now. I went out and bought the allen socket that the book claims.

After looking, it seems like it has some L19 head studs in there. Which is cool, saves me 400 bucks... But, i cant seem to find what fits on there to take them back off??? Anyone have any ideas??

I figured it out, and got it out of there. Found out that it has some Weisco pistons in it, that look fairly new. So apparently somebody has been in the lower end of it before... That just saved me some money right there, maybe i just need to build the head and the turbo now.
