It has surface cracks and signs of heat? The machinist said by the time they resurfaced it it would be too thin to be "reliable". This was my Dads car. He was pretty weak the last few years and had problems shifting it. I am guessing that is the damage the machinist was talking about?

Of course, I have no idea how competent your mechanic would be at estimating how much material would need to be machined from the flywheel to eliminate the "surface cracks". He might be 100% correct about the flywheel ending up "too thin", or he might be talking completely out of his hat.

Very True..... I am kinda at his mercy .... I mean I looked at it and I can see many tiny cracks and a lot of "blue", but I don't know the process and how deep they go? I know it has been 10 years since it was resurfaced and since then it has had the clutch replaced once already? Everyone I show the picture to says it is junk, replace it???? This is when I really wish my Dad was still alive, he knew that car inside and out!

IMO, it can't normally be determined from anyone simply looking at the flywheel whether it's "junk" or not. It's current thickness needs to be measured... and then someone who's experienced at resurfacing flywheels could probably give a good estimation of success with another re-surfacing.

I'm just pulling numbers out of the air... but let's say that this particular flywheel (when new) has 0.100" of material that can be safely removed during re-surfacing(s). And let's say that 0.030" is normally removed during each resurfacing. That would give at least three opportunities to re-surface a flywheel.

If someone could supply you with the original thickness of this flywheel, then it would be much easier to determine if this particular flywheel can be re-surfaced again. It may turn out that there's plenty of meat left on it.

Good discussion in this thread - My flywheel...please take at look..need advice

Luck be in my corner and THANK YOU Feirofool for selling me a good flywheel! Much appreciated to get my Dad's car back on the road.

And thank you to those that posted links and suggestions, I greatly appreciate the knowledge on this forum.
