I'm refreshing this new to me 617 and ran in to a snag while preforming a leak down test...

I did set the valves before this test.

From 80 psi to glow plugs. Cold engine.
#1. 12psi drop 15%, mostly exhaust valve, some piston rings.
#2. 6psi drop 7.5%, mostly exhaust valve, some piston rings.
#3. 5psi drop 6.25%, half at intake valve other half piston rings.
#4. 5psi drop 6.25%, equally at intake, exhaust valves and rings.
#5. 5psi drop 6.25%, some intake valve rest at piston rings.

All the piston rings seemed to leak equally.
There is no blow by between any of the cylinders and none of the injectors were leaking.
Numbers 1&2 are closest to the EGR valve, massive carbon buildup.

I really don't want to take the head off to lap the valves. I heard that BMW has a procedure for walnut blasting...

Video i made...

get the third valve adjust wrench, and rotate the spring collar with slight tension on the valve face. rotating the face can seat the valves and clean up the grit that's likely on them.

Thanks I was going to take the rack off for that.

I came across this statement but it can't be correct.

From 80 psi to glow plugs. Cold engine after closing all the valve leeks

#1. 65psi dry, 73psi wet 13% drop
#2. 74psi dry, 74psi wet 7.5% drop
#3. 74psi dry, 74psi wet 7.5% drop
#4. 76psi dry, 76psi wet 5% drop
#5. 60psi dry, 68psi wet 20% drop

All at the rings now, I did spray **** load of carb cleaner in there to close those valves up.

I'm not understanding why the engine was removed from the car? Usually the easiest way to clean all the gunk out of an engine, is to replace the injectors, filters, primer and other normal ware items that are over looked. Do a valve adjustment and then start driving the car like you stole it. Usually when you pull the engine, you have a good replacement to put in its place....rebuilding the engine is not a cheap job....so most people get everything up to spec and drive it till its dead.

Welllll if you ask...
My original 300D sits in my converted form 3.9 V8 Land Rover but last month front of the crank on it broke off. So I went to a local pick and pull and scored this one for $120, now I know what you'll say, but I don't feel like doing this in a year again.

Anyho, I'm going to tilt this thing on it's side and fill it up with Kerosine. Day or two should free things up.

617 porn..

That looks fantastic!
