Okay the Ranger is working perfect
So now on to the 230K (I have no idea whats been done to it) 1989 Bronco II 2.9L Manual
It has Bad lifter/valvetrain noise
I cant imagine the heads making it 230K without replacement but I can imagine someone doing it and not re lashing it.
No amount of warming up is reducing the noise and I do have pressure. although once it (The clatter)disappeared completely for a few minutes.
I popped the valve covers and discovered:
1. The rubbers for the PCV inlet and Blowby fittings are turned into mush.
2. Whoever replaced the covers last got by with silicone on one side and no gasket while the other side still had a rock hard gasket left and no silicone.
3. The underside of the covers was 1/4 thick with sludge... the PCV oil sling cover inside was nearly clogged.
so what does this have to do with HAYNES manuals.
Page 78, number 8 under lifter inspection "Replace entire lifter if plunger is not free in the body."
I thought play in a hydraulic lifter is a bad thing? Or is this read to mean once the lifter IS REMOVED the plunger is free. I have not checked every rocker but there is some substantial movement in the pushrods not associated with the feel of a loose valve lash.
THAT BEING SAID... as I don't want to tear this engine down yet and get into lifter and cam replacement (engine does not smoke)
Considering the nasty sludge build up... and the affect sludge has on oiling those lifters.. what would yall do. Apparently someone I think already poured some nasty shit in there... REMEMBER the gummy rubber on the blowby and PCV inlets.
So based on the highlights what would you do first tighten the lash first or clean the covers, pop them back on and try and flush the engine and oil pump sump?
What threw me was the engine bay was clean enough to eat off of.
