Probably becuase I just returned the mounts I bought last week to the store yesterday....

How do you tell if the mounts are OK or not? Is there a wobble meter I should invest in?

Hookedon210s has been helping me a lot with this. He had a look at the car (we live in the same city) and told me the mounts are shot. They were. I took them out and they were pancakes. I replaced them with mounts from the 300D - Hookedon210s said these are better becuase they're harder. Also, he said it is worth the money to get good mounts, ie mercedes mounts, not OEM. I replaced the shock absorber which hides under the one mount on the driver side.

Anyway, the car drives a lot differently. The engine definately feels smoother and quieter. However, that infernal whumping is still there! It is sort of smoother now, but it is still noticeable at 60mph. It is a cyclic vibration that feels like it is coming from the engine or tranny. It increases in frequency when I hit the gas. At 65 it dissapears slowly. I've tightened the flex plate, replaced the motor mounts, checked the tranny mount - what could it be! Maybe it is the tranny mount - it was shorter byabout 1/4 " than a new one. I didn't think that would make a difference, but maybe it would.

Any ideas?

Motor mount install tips.
For those of you attempting this the first time, save yourself a few hours of swearing and frustration - there is one allen key bolt in the mount on the driver side that is hard to get to. It is the one that is nearest the engine and under the protective plate that goes over the mount. The way to get to this best is to

1. support the engine under the oil tray (use a piece of wood and lift jack)
2. release the main 8mm allen bolt that holds the engine onto the mount (do this from under the car), then
3. lift the engine carefully using the jack. Be sure you have released the engine stop between the engine and tranny so the engine can raise up. ALso loosen the fan shroud so the fan doesnt' hit it.
4. the engine should lift high enough to allow you to get to the allen bolt holding the mount to the frame from on top. You will probably have to loosen the 8mm bolt on the other side engine mount quite a bit first - I did.

BTW, recommended tools - 6mm and 8mm allen wrench sockets so you can use a air rachet or click type wrench.

I changed IPs a couple months ago, and this thread got hung up with 176 other emails at the old IP. If you still have the problem, it might be the anti hop kit that is bolte between the cross member and oil pan. You can loosen the bolt and let the engine settle to the new position.

AutoZen, yes, I still have the problem. Thanks for replying.

By anti hop kit, do you mean the engine stop -= the kinda L shaped mount thing that stops the engine from lifting too much? My car didn't have one of those, but I installed one, but the whumping continues....

That's the one. Loosen the bolt and move the engine around to see if it resets in a different position.
