Q: There is a kind of a loud tapping in the motor when I start it up, then when I drive, it comes and it goes.
Do you think it is the lifters?
I put some stuff in the crankcase to quiet noisy lifters but it didn't work!
A: These cars had a problem with a weakening oil pump losing pressure..... have a mechanical oil pressure test done.... It is easy to change the pump itself although a new pump costs a few hundred.... Ed

Q: I'm having trouble with the height adjustor. The front seems to have locked in the 'hi' position even though the dash is reading the normal position.
When I engage the heighth, the rear comes up to level, but then the dash will show the heighth flipping from hi to normal and the rear will start to deflate. Is there a manual way to fix this or do I need to involve a mechanic?
A: Without the book of information, you'll need the mechanic..... Ed
Q: I drove the car to on a 450 mile trip back home. I wanted to change the oil just in case so I added a half a quart of Marvel Oil befor I left to clean out the engine. It ran like a champ until the second day that I was home. The loudest tapping started and kept up even after I changed the oil and a bottle of a heavy mechanics mix that was designed to quiet lifter noise. It worked great after a couple of days and then kept working for three more days before the sound came back again.
I assume its the lifters, but why would they go bad after running so well on the trip? What can I do without having to replace the lifters?
If I have to replace the lifters, is it a major task?
Any insight would be appreciated!
A: Try adding a litre of automatic trans oil to the engine and driving for a few weeks to wash the dirt out that you have washed around inside the engine. Ed
