Replacing my 602 cylinder head. Advice requested....
I'm sure I'll have a few more questions, but these should get me started for now.
So I'm just about ready to remove the head, I only need to pull the chain guide pins, and remove the heater tube(?) that connects to the head near the firewall. Which leads me to my first question: 1. How do you go about removing this tube? It looks like it should just pull out of the head, but I cant move it. 2. Is it standard procedure to replace the chain guide, or can I reuse it? 3. I'm also going to replace the vacuum pump while I'm at it. Is there anything I need to know about replacing the pump, or is it simply a matter of removing the old pump and bolting in the new one? (engine is at TDC) 4. I'm going to be replacing the old head with a remanufactured head from Metric Motors. When I asked about head gasket thickness, they recommend a thicker than stock gasket that they sell for $300.00! This seems fairly outrageous to me. Do you know if I would be able to source a thicker gasket (that is still oem quality) from somewhere else for less money? Or is around $300.00 the going rate for thicker gaskets? 5. Are you aware of a more in depth write up of R&R the head anywhere? I have the factory manual, but it leaves much to be desired in terms of detail. Also, any, and I mean ANY tips/information you guys have will be greatly appreciated.

Keep your fingers crossed & hope Roy (whunter) tunes in with his usual priceless advice!!
Or better still, give him a call. Did they tell you why you need a thicker head gasket?

Haha...I actually spoke to Roy on the phone prior to starting the project. I may have to call him again.
I assume I need a thicker gasket because they removed some aluminum when flattening the head? They didn't get into details in the email they sent.

Maybe some one else can tune in on this though.

1. There is a semicircular clip on it. After removing that you pull the line out (it's tight).
3. Vacuum pump is bolt on, nothing special. 4. There are part numbers for oversize gaskets, with different thickness specs. Presumably for prechamber clearance. Try the dealer? Then again if this were important they wouldn't merely be recommending it, they'd be insisting on it. |
