Either: (a) your oil pump is worn out and is not providing sufficient pressure.
Or (b) Your Valve train(lifters,push rods,springs etc)are worm out and in need of replacement.
You could try "Lucas oil treatment" this is used at most Drag Racing tracks, and it certainly couldn't hurt the situation and may even help.

I changed my oil last night with my boy friend who does frequent oil changes. Afterwords, my transmission started shifting extremely hard and late. Please help. I do not believe he drained the tranny...


e: subaru legacy transmission dipstick Transmission dip stick is behind the engine in front of driver side firewall. Move a few hoses out of the way, look down and you'll see it has a yellow top.
Other side (passenger) lower down yet, again move a few hoses aside, yellow top handle, you'll find the shorter differential dip stick.
In either case, if your gaze reaches the ground, you've gone too far.

Bought a 92 Subaru Legacy wagon that started a top-side ticking sound last night, first time. Of course didn't hear that when I test drove. Someone told me it could be valves?


hi yes ticking in early model subarus is very a common valve/lifter prob in most cases a decent oil change or anti ticking treatment can quieten it or stop the noise altogether however in some cases the noisy part may be damaged beyond repair and need to be replaced

I need the tappet setting code for a 1995 ford econovan.tappets are noisy.


There's NO code for noisy lifters. Depending on miles and previous maintenance (oil changes, etc) your lofters are probably worn. They need to be replaced and you might have an oil pressure test done to make sure there's is adequate oil pressure.

My car is making a ticking noise


It's most likely your tappets! Check your engine oil level, when this is low the hydraulic tappets get noisier or they could be just worn!

Hydrolic lifters making a taping noise


First thing to do is change oil and filter. Hopefully it has not done this long and has hard faced the shims. Good luck and have a good day.

Loud Lifter possibly stuck! Help please!!


The ticking lifter on the Loyale is a common problem. There's a small o-ring between the cam tower and the head that, after so many hundreds of thousands of miles, would "fail" (not to a dangerous point) and the lifters would be partially starved of oil. It's not THAT serious... they can go hundreds of thousands of more miles like that. If you replace that o-ring, replace it with a spring reinforced ring so it doesn't fail. Those can be found at wwwdotthepartsbindotcom. As for the Legacy... those early 2.5s were cruddy. I've seen alot of them throw rods, lock up WAY before they should have. Best bet would be to replace it with a slightly underpowered but bullet-proof early model Legacy EJ22 or go with a newer EJ25. I would just go with the 2.2L.

Both head gaskets have to be replaced and the heads need to be resurfaced, be sure you go thru the torque specs and sequence correctly, it is a strange process, but has to be done. subaru puts out a product called cooling system conditioner, it's advised to install this.
