Looks spotless! How did you clean things so far? It looks like you have put in new valve guides already...
What jobs are you able to do in your garage and what (if any) are you taking to a machine shop? Thanks for the pictures, very nice! |

Cleaning was just solvent tank and then glass bead for the heads. The guides are the old original ones and measure out good. I've got access to a serdi valve and seat machine and will recut the seats there after cleaning up the ports. Then I'm getting the p&c's measured and if good honed using a silicon exposure process.

You have the heads removed, disassembled and cleaned and you're not going to replace the guides? These motors are known for premature wear of valve guides. What's the point here?

Is there a reason to replace them if they are not worn? I figure why take a chance on a new one being that the existing ones are proven.

One reason to replace valve guides is that the old guides WILL wear out sooner than later, and newer guides are made from more resilient material .... they'll last forever.....so they say.... This is an older thread from Rennlist ... pretty interesting...

Thanx for the info Jim. I didn't realize porsche was using some inferior materials for the guides. Does anyone know what it is? What are the good ones to get?

Oh I wouldn't say that Porsche used inferior materials. It's just that advances in metallurgy and manufacturing techniques result in BETTER parts than were available 25 years ago.....

You will be doing this again sooner rather than later if you don't do it now. The 84-89 Carrera's are well known for valve guides going well before 100,000 miles. Mine were shot at 88,000. Per Steve Weiner that phosphorus bronze is what they are made of except they are harder than the Porsche valve stems. Are you replacing your exhaust side cylinder studs with steel? BTW the heads look great.

My valve guides had to be replaced 600 miles after an engine rebuild. I now suspect they reused the old ones.

Rods: Triple checked both ends, installed ARP bolts, shot peened, glass beaded, and weight balanced. I was extremely surprised how good everything measured and weighed. Now to get my bearings back from Calico and start assembling.
