Car Forum / BMW Cars / April 2004Oh dear...[E30 (1988 325i)]
Just had a call from my garage saying that it does not make sense to change the cambelt now seeing that the head gasket needs changing and oil could drop onto the belt during the change- Does this make sense? How many man hours of work are we talking about here? Sigh... VJ > Just had a call from my garage saying that it does not make sense to change > the cambelt now seeing that > the head gasket needs changing and oil could drop onto the belt during the > change- > > Does this make sense? It makes sense that you would want to do both things at the same time. > How many man hours of work are we talking about here? Not sure of the exact flat rate, but it will be a hefty bill, no doubt. What I would not do is procrastinate the job for to long if you a due for a timing belt. If the belt goes before you do the head gasket you'll be adding a rebuilt head to the cost of the job, possibly more... -Fred W Update: It is actually "only" the cylinder head seal which needs replacing. This is somehwta comforting, I suppose I can drive for sometime just need to keep topping up the oil supply. Should I still go ahead and change the cambelt seeing that I have no record whatsoever when it was changed last?

Do you mean valve cover gasket or Cylinder head gasket or something else? > Should I still go ahead and change the cambelt seeing that I have no record > whatsoever when it was changed > last? I think you already know the answer. Change that puppy! ...like, yesterday! -Fred W > Update: > > It is actually "only" the cylinder head seal which needs replacing.

(behind the cam pulley). > Should I still go ahead and change the cambelt seeing that I have no record > whatsoever when it was changed > last? Damn right! Change it now. The pulley has to come off anyway so change the camshaft oil-seal and do the valve clearance adjustment at the same time. It's all done then and you can relax. About 2 hours work total. HTH, JB Vjay Take a look at this page, and then go get a new cambelt.. your M20 inline six is an 'interference' engine, as was the venerable M40 inline 4.. http://www.bmwworld.com/engines/m20.htm > Update: > [quoted text clipped - 23 lines] > > > > VJ I hear you guys. Being a novice I am not quite sure whether I should "trust" the garage's statement that they do not recommend changing the cambelt unless I changed the cylinder head seal (slight leak). I personally would go ahead and change the cambelt anyway seeing that it is THE vital part of the M20 engine. One question remains though - is there any harm with a bit of oil dripping onto the belt? Thanks guys VJay > Vjay > [quoted text clipped - 33 lines] > > > > > > VJ > I hear you guys. > [quoted text clipped - 4 lines] > question remains though - is there any harm with a bit of oil dripping onto > the belt? Yes. Oil on the belt can cause it to breakdown prematurely (ie even *before* the nominal change mileage). But OTOH, not chnaging a belt that is due or overdue is foolish too, since that one no doubt has been oil contaminated too. I'm sure they are trying to save you from having to pay the labor twice, but best bet is just get it all fixed now before the old and oiley belt does have a chance to go. -Fred W Amen to that! I actually had my timing belt break recently after only ~40K Km (1/2 the recommended period between changes) and only recently figured that this had happened because 2 of my piston rings were broken and the car was burning a lot of oil which probably found a way to seep into the timing belt and lead to its premature breaking (at least I would like to think that to keep the thought from suing the dealership becoming a reality!) I am now in the process of replacing the whole engine with a used one from a 90' 525i with ~170K Km on it. I hope its a good one! Imad > > [quoted text clipped - 28 lines] > > They should only charge you 1/2 hr. more to change the camshaft seal while they are doing the belt. Insist that they use a BMW seal. Better yet, supply the seal that you buy from a dealer. It may piss them off, but they won't turn the job down, and you know that you have the right part. . > Just had a call from my garage saying that it does not make sense to change > the cambelt now seeing that [quoted text clipped - 8 lines] > > VJ |
