Head Rebuild

[Leo991!]

Hello All,

So it looks like I may have an issue with one of the valves on my 182 track car, my mechanic (who also has a 182 track car) seems to think one of the cylinders is losing compression. When cranking the car over with the coil pack unplugged you can hear one of the cylinders making a different tone of noise. The car seems to be running really rich when I moved it out of the garage this morning, possibly an exhaust valve that has chipped??

So - he will removed the head, get it skimmed etc & I need to supply the valves, I'll also look to change the cams for some 197 ones, if anyone has any for sale then please message me!

Question - do I need to replace anything else i.e. valve guides? do I need upgraded valve springs with the 197 cams or do I just use the old ones?

I'm looking at the Wossner uprated valve set (both inlet & exhaust) - are there any other makes that I should look at?

Cheers,

Pete

I'd imagine Wossner would be good.

Supertech is another thats used a lot.

These engines are well know for dropping valves.

I'm not saying yours has, but maybe hold fire buying anything till you've got the head off and have a clear idea what is wrong.

I assume he’s done a leak down test to confirm the valves the likley issue?

I'm going through the same thing, I've got 130psi on three cylinders and 90 on the forth, safe to say I'll probably need a full head rebuild.
