I finally completed the purchase of my 78 wagon, after having it for almost a month! Driving it around I've noticed a bit of noise in the engine, might be valve slap. Is the adjustment process about the same as a Chevy: while the engine is running loosen the nut, tighten until it stops making noise and then give it an extra 1/2 turn?

 

I can only imagine that the horizontally opposed banks make a mess with the oil doing it this way. Any tips on avoiding lubing the rest of the engine compartment?

Valve adjustment should be done on a cold engine and not while it is running!

 

There is a tool that appears on eBay every now and then which makes the whole process slightly easier. Like this one which did not sell.

Hey.

 

Have a look at this.
