spark plug tube seal leak...

[jwardmls]

hello. i drive a 1991 318is, and i have a slight oil leak in the spark plug tube. i was wondering if i could use a high temp silicone gasket maker to tempararaly fix this problem...? if not where is the best place to buy a valve cover gasket set that includes the plug tube seals? also does anybody kno how hard it would be to replace the timing belt myself, or if i should take it to a pro?

yes, u can... but you'll still need to remove the valve cover. the better idea is to change the valve cover gaskets. they're cheap.

i often use Speedy Car Parts - Audi parts BMW parts Honda parts Ford parts Chevy parts Dodge parts GMC parts Jaguar parts Mercedes parts Nissan parts Porsche parts Land Rover parts Saab parts Toyota parts Volvo parts Volkswagen parts VW parts for the parts i need. Others here use online sites dedicated to BMW parts alone.

Timing belt replacement. If u haven't done one before, better to seek the assistance of a mech, or have it done. wrong alignment of the crank and cam will bend or break your valves.

thanks for the input. ive done a couple of timing belt replacements before on honda's, but i havent touched a timing chain, and i had read somewhere that my car has a chain instead of a belt. so... any differince in replacing the two?

[darkhorse737]

you are correct!. your car uses a timing chain....

Theoretically, timing chains last the life of your engine. so unless u hear grinding noises from the chain guides wearing out, you'll be fine ;-)

the timing chain doesnt have to be touched for the valve cover replacement.... yeah replace it!

there is a slight noise coming from the front of my motor, but i dont think its my timing chain... i had heard that timing chains were supposed to last the life of the car, and i know this isnt saying much, but i broke a timng chain on an older dodge shaddow a few years back and since then ive wondered about that theory. with european built cars i dont think i have a whole lot to worry about though. thank you guys for the help!

a little off subject but does anybody kno how hard it might be to turbo charge the m42? i kno the basics... but would i need to change the internals?... or should i build it n/a? im just looking at different options.
