hi, like i mentioned on another tread i bougth a 1984 240 dl recently, so in order to start a maintenance routine on it, i change the oil, oil filter, air filter, new sparks and wires. but after the oil change, the engine starts to make a noice. seem to be the lifters but im not sure. I use 10w-30w oil. Any suggestion about the sound?? thanks again for the help!!!

 

verify you put enough oil in it.


I suppose its possible the engine is very tired and worn out and has 'piston slap' and/or valve clearance problems, and the previous owner put heavy weight oil in it to quiet it down. the good news is, they will run for years with a bit of piston slap. if it IS valve lifter noise, the valve clearance should be checked and shimmed if neccessary.

 

Change your oil to 10w40,its a little thicker.

 

I started to get piston slap around 175K miles and now have 336K with the same noise. It sounds like a quiet diesel when idling and hasn't been a performance issue.

 

i used 5 quarts, thanks for the info!!

 

ok thanks ,, i will try it , on the next oil change!!

 

the use of metal lube is safe??

 

hmm? not sure what you're asking about.

 

its about the antifriction
engine treatment metal lube

 

thats an oil additive? I've never liked using any of those, any proper engine oil has all the additives it needs.

oil *IS* antifriction.

 

thanks so much for the tip,!!
