I did a full oil filter and oil change today. I used 25w60 instead of 20w60 as we are coming into summer and I not longer have the oil cooler fitted to the engine.

Just took the bike for a run. I noticed that the clatter from the heads is way louder.

At idle the oil light is flickering almost in time with the idle speed.

This to me is not a good thing to have happening. Never seen the oil light stay on for more than a few seconds at start up.

Could it be the grade of oil I am using is too thick? I have done nothing out of the normal with this oil change than change the grade of oil I use.

You have only gone up to 25 w from 20w. That is not that big a difference. I am much more worried that you got the oil filter correctly installed. I asume you have the correct filter since you no longer have the cooler.

What year is your engine?

What year did that isue with the locating pin falling out of the front main bearing start?

Yep got the right oil filter. As per this image.

The engine number for the R80 parts I am using is 82414815 then this is stamped below the engine number on the left lower side of the casing under the left cylinder. 802VB

I am assuming the 82 at the start means that the engine was made in 1982?

82414815. Unusual number. Using the last 7 letters as the vin to check at http://www.realoem.com/bmw/select.do?kind=M&arch=0 it says your riding a 1988 730i sedan! Ross, you need to ensure the vin is correct.

Yours is a monolever isn't it? They started in 1985?

I think you need to go back one step.

Redo the oil/oil filter, taking extra notice of the o-ring etc...did you check that little ball valve way in there? Not saying it's the problem, just "did you check it" given the opportunity?

Mine is a 94 R100RT mono badged as a LT. It has a 82 R80 engine with my R100 barrels and heads fitted. This was due to the pulled engine stud not being able to be fixed.

I did check the ball and it had good resistance when I prodded it with a stiff bit of wire.

I will check the oil ring again. I am sure it went in correctly but will check it again.

Oh yeah...I remember now. What's the vin number pressed into the case at the dipstick?

Hang on the only thing I did different was put a paper gasket between the engine block and the oil filter cover. It didn't have one when I took that cover off this morning to get the filter out.
