However, after starting, it hates the cold and is very noisy when the temperature is below 5 degrees c, or about 50F until the engine temp reaches normal..

Also, if I put the "ultra" BP deisel fuel in, the engine runs more quietly both hot and cold.

I would imagine that I could quieten the engine by adjusting / replacing something - but is it a garage or a diy task?

Does the car still have the three sound deadening panels secured to the under car--next time on a lift look under the rad, crankcase and transmission!!


And remember you have a mechanical fuel pump and injectors----noisy at low rpm's


What viscosity of oil do you use!!

Check for air bubbles in fuel tubings.
If tubings are over 10 years old- replace them
Other thing to check would be chain tensioner. They are oil-charged and cold oil is taking longer to fill them up.

No idea what oil is in there, probably 20/50 Castrol. As to the mechanical pump and injectors being noisy, when the engine is warm, it is pretty quiet for a diesel.. but I do understand that by then, the metal parts have expanded with the heat...

I'll look for those 3 panels you mention thanks Plutoe.

Air bubbles in fuel tubings... replace as required - OK thats one for the local garage! As is the chain tensioner...

I'm not a mechanic so again, off to the garage for that option, but I really like the logic of the cold oil taking longer to fill them up...

Really appreciate the ideas, even though the car is old, its a great drive and with it being so well behaved when its warm I want to "look after it" if there are early signs of trouble like the extra noise when its under "normal" temperature.

I'll look for those 3 panels you mention, and maybe I sould use a different oil, 10/40?

thanks Plutoe.

Probably 20/50 Castrol...what makes you say that?
Anyway...to be sure, change it for a 5/40 fully synthetic.

JN27

I can do that. As to why I said "probably", thats what I thought my local garage used.

When I last changed the oil, thats what I put in a car.

I'll ask to be certain...

Now I am feeling old and a little out of touch!

Appreciate the feedback..
