Thanks MM -- I have never seen that. What engines does it apply to? Does it apply to the '89 2.7 head?

Hey Tom. The 2.7 cylinder head has a unique check valve. It’s a more sophisticated piece; probably expensive, but same simple one-way function.

That's why I was asking -- wondering if I could use the 951 check valve instead... ?

One-week update: The engine is running great. It idles smoothly, revs quickly, and is surprisingly quiet. The new engine mounts made a huge improvement in overall driving quality, and even the A/C is working again. I’ve run into a new issue with the cooling system, which I’ll cover in a separate topic.

He left last week on a test drive and never came back. I know the feeling
