Newbie questions 603 related

[Vladamir]

Hi,

I have scanned through various posts, and the problems I have got with my car could be a combination of factors....I would be grateful if you guys could point me in the right direction.

Firstly the car is a 1988 w124 300D non turbo with a 603 engine. Car has done 141,000 miles and has a full service history.

Problem 1, car has a rough idle in the warming up stage. If I drive off and shortly thereafter come to a stop the car will vibrate quite badly....the rev needle stays rock steady at 650rpm.....is this engine mounts or injector related?......car no longer vibrates once the engine is warm.

I don't notice any nailing, however, it does appear that one of my lifters is noisy....loud ticking noise that goes away once the engine is warm and once I get past 1500rpm. As a seperate question if I have lifter tick, does this damage the engine or can I ignore it.

I understand that changing to synthetic may help...I have yet to do this.

Problem 2: Every time I put the transmission into reverse the car judders quite badly as I move backwards and will happen irrespective of whether the engine is hot or cold....is this linked to problem one, ie; is it likely to be the transmission mount and is it a prop-shaft mount or something else.

Problem 3; checked transmission oil...nice and red...however when I dip the stick the oil level goes way past the marks on the stick. Am I right in thinking that you check the level when the oil is hot and engine is idling?....will I damage anything if I have too much oil in the transmission?

Other than the problems mentioned above the car runs fine, no smoking, plenty of power and good fuel economy.

Any help would be appreciated as I just want to clear these nagging faults and put my mind at rest.

Cheers
