Service-What to change?

[jon_d_h]

Hi

I am going to do a decent service on my 325 and was wondering what the main things to change are. I have noticed a loss of performance recently and was wondering if a good service would sort it out. So far I am going to change the oil, oil filter and spark plugs. Anyone know anything else that I could change?

Cheers

Air filter, fuel filter, set the valve gaps. Check the rotor arm distributer cap, only renew these if they are obviously worn as they are £££. You could give the afm and icv a clean out with some carb cleaner.

Cam belt and tensioner are good for peace of mind unless you know when they where changed last, and if you are going to do that you may aswell do the waterpump as its only another three bolts.

hope that helps maggs

Ok, cheers. I know that the cam belt was only changed a couple thousand miles ago so that wont need doing. Il get the main things ordered

Are these the best spark plugs to get?

Got some parts today, Was looking at doing the valve gap adjustment as I will be changing my spark plugs so could do it with them out. Is there any way I can tell if they need doing or is it worth doing them?

Also, where is the fuel filter located?

Seems easy enough, not done it on mine yet though

I can confirm that it's easy peasy. Just need to make sure you put it in the right way round

fuel filter is right by the nearside rear beam bush.
Always check/adjust clearances at a service, you'll regret not doing so. A good M20 should run silky smooth.
You'll want to renew your coolant too for the winter, make sure it's the right consistency for the colder weather

Just removed the spark plugs. They were NGK ZGR5A. I am fitting NGK BPR6ES's. Will this be ok? Its a 1989 325?

Yes.

[jon_d_h]

ok, cheers

Im, doing the valve adjustment now, when using the feeler guage, should it be tight to remove or, fairly easy or aslong as I can remove it, it will be ok?

Cheers

[Bob_S]

with a slight bit of resistance but not tight.

[jon_d_h]

Cant seem to find the fuel filter anywhere? Any ideas

[Speedtouch]

Probably under the nearside rear floorpan (aft of the wheel). It should have a black plastic cover hiding it.

Ok, Il have a look tomorrow. I finished the valve clearances and the car wont idle very well now. When coming to a junction, it stalls when I put the clutch in sometimes. Could this have anything to do with the valve clearances being to tight or loose?
