Camshaft timing findings

Reality is that most stuff that comes out of the pump is very avarage, no matter what part of the country a person's in. It is getting better with Ethanol blends though. Could have a valve seal issue, maybe even a guide, how do the valve stems & back sides of valve heads look when looking down/in to the ports? Gummed up at all?

Ryan,

Thanks again for your input. Not sure about the fuel here and the only additive over the years has been Sta-bil for storage off and on. I imagine it sucks here, but we do have one station (Union 76) in the Honolulu area that sells several types of racing fuel, but have not checked it out. Looking down into the ports the intake side is really clean except for the secondaries that are a little gummed, but looks normal. The exhaust side is another story and maybe I'll be able to take some pics later as they look very gummed up. The heads are in the process of being shipped to Greg Van Deventer so we'll see what he finds when rebuilding these. Gotta head to work so thanks again.

Lee,

Thanks again for the TIPS. I might have to try it after I get the rebuilt motor broken in. I did not even have a chance to try the AMSOIL 10W-40 and wasted it when I found the piece of metal in the oil from the key on the crank.

2. Where did you get the Timing pins J37326?
3. Where did you get the J38098 crankshaft locator?

Dynomite,

I got all the tools from Bill Kirchoffer in the ZR-1 Registry in the LT5 parts/tools:

Not sure what he has in stock right now. My last order he was out of some of the items and not sure when he would get another batch.

Good luck with your project and I see you are doing some awesome stuff.

You're welcome and great idea. I hope all is found well. I'm going to try to degree mine in when I reassembly if I can figure it out.

Let us know when you get er running

Thanks, I'm sure we'll be hearing a lot from you and I'll be sure to update as I make progress. Try to make it to the 2010 Gathering in May; I'm flying in from Hawaii. It will be a several more months for me to get er running.
