Best method to correct valve clearance after HG job?

[4flyer]

Putting my engine back together after getting a cracked head. I was checking clearances and many of the valve clearances are out of spec and on one of them, there seems to be no clearance whatsoever.

Probably my fault. With the new head that came from Clearwater, my buddy held it upside down and all the buckets fell out.

On the old head, the marking I put on them all got worn off so putting them back was a guess.

Now most of the tolerances are bad. Best way forward correcting this? Also, if I were to re-shim them with the crankshaft installed, is there a way to do it without the SST?

Thanks!

I think you are in for a lot of trial and error!

Get the special tool to compress the valve/bucket. Leave the intake cam in place, remove the exhaust cam (after putting in the lock bolt!). That seems to be the best compromise for access and keeping alignment if the heads are already installed and timing belt is in place.

Get the clearances, remove the buckets, do the math. You should be able to get them all swapped to their correct locations... though since you likely swapped the bucket+shim, you may want to remove both cams and swap around buckets+shims...

I'd go through the Timmy the Toolman video and adapt his suggestions to your specific situation.

Good luck!

Here's my results when I did my valves - I was able to swap a few and then only had to buy a few:

Sounds good. My engine is completely torn down at the moment. No timing belt. And I don't have that tool.

I think given the situation, it might be best to:

1. Remove both camshafts as the TB is not installed
2. Measure the shim thickness as I already know clearance
3. Calculate the new shim size
4. Swap out
5. Re-assemble

thoughts?

Yes, if the head is off the engine, just remove the cams and see if you can swap the buckets to their correct positions. Watch for cam cap orientation and position and make sure you have the exhaust cam scissor gear lock bolt in place when you remove either cam.
