Well I stand corrected on the lifters. I know there are no stinkin pushrods so I figured no reason for lifters plus I dont really see em in this pic....Where are they at Jeff? do they really call em lifters? Can you point em out in the pic's for me. Thnx....inquiring minds wanna know...lol are they hydraulic and can they collapse and make the ticking sound?

I'm

at what I said about the "in & out" thing Jeff! I should have realized that with our comp ratio & flattop/dished pistons the chamber volume has to be waaay small! Thank you Sensi Master!

The lifters are the 'hat' lookin' things over the valve springs in the line drawing Bryan. The rockers act directly on the lifter bottom.

Hey, yea, how does one of those little buggers come loose? I would have thought that they would have been "loc-tighted' in upon assembly??? This chit makes me wanna take my stuff apart again and check all those little screws....my luck I'd loose one of them & they would punch a hole thru the chamber to a water jacket.

Okay another dumb Q from the weed eater

.....Is it possible to fix, by welding, any damage to the chamber and then clean up the weld so the chamber configuration is close to original condition or is the head "junk"? I mean is ain't like we can call Dart or anyone else and get a new head? We can still buy new sleeves, right???

Bill, if I was filthy rich...... I'd come out there but not to work on the car. I'd do one of those pranks like on overhauling....steal it & have the car sent to be "overhauled" by a dream team of ZR-1 specialists.....unfortunately, I'm just filthy. I just finished boiler maintenance, #6 fuel fired! My collar isn't even blue, it's black!

Good luck with this, Bill.

Kind of hard for the screw to overcome gravity and magically flow out the exhaust valve as well

Yes, it can be repaired. Head would need to be welded and machined back to specs. Cheap heads are available.

Here is the damage a screw can cause

IT AIN'T PURDY

RedZR · 10-15-2006

WOW !!
Was that caused by a secondary screw that came loose also? Any idea how often that happens?

OK We are back from our weekend run. So now it’s back to the problem at hand. As I dig deeper into my LT5 I get more questions. I have brought #1 to TDC on the compression stroke, but can’t find any marks on the crank pulley. Is there some kind of mark there?
For those of you following along in my attempt to gain knowledge I will be posting pictures to my yahoo photo album. Here is a link

Tom At one time my job was to make steam, but my Uncle Sam wouldn’t let me clean in there, Thanks for the offer, we could learn together.

Jeff that head looks terrible. I hope mine doesn’t look that bad.

More to come as I proceed

Bill · 10-19-2006

Here is an up date. I have been treading water for the last couple of days. I keep looking at the cams and worry that I wonâ€™t be able to get them back in right. I finally found my copy of the LT5 training tapes and now feel a lot better about proceeding. From the tapes I learned that the cam chain tensioner is not re usable. Is this true and is it still available? Found that my crank pulley does not have a timing mark on it. This made life a little difficult but was able to overcome. I painted a mark on the pulley for future reference; I hope I never need it.
More updates as I proceed.

Brian I'll post a picture of a "cam follower" when I get them out

Bill · 10-19-2006

A little more progress. The cams are out, I hope I can get them pack in correctly. Here is a picture of the head with out the cams.

and just for you Brian, I pulled the 2 â€œliftersâ€ out. The top one is an intake the lower one is an exhaust. They look the same to me, but that is where they came from.
