HI!
I new at forum but unfortunetely. I have got a problem with my engine. Car has done 91000 miles and is running on Mobil s 10w 40, few days ago start tapping and I dont know what to do with this. I am oryginaly form Poland so maybe somebody will advise me where I shoul go and how expencive it can be to change the tappers. Obviously I dont want garrage to rip me off . I live in Lincoln
cheers

has it started since using the mobil 1?

what age and model?

the mobil 1 is not well suited imho.. and it may just be a case of running different oil if it is only the tappets making the noise..

the 99 onward cars do develop a tapping / knocking noise when the cam belt tension is on it's way out and the other obvious tap / knock is big end bearings but as you called it a tapping.. hopefully it is just the tappets, depending on model and therefore type of tappets it may be a dropped shim, or clearance problem or just simply the oil if hydraulic tappets.

Lincoln you have scoobyclinic or zen performance both not a mega distance away

It is some sort of metalic sound tapping, knocking when the car is warm, when is cold is ok and You cant hear that. My car is a Jap import, 1995 wrx impreza turbo, automatic and hopefuly there is only a tappets not bearings . Anyway, was running fine when ive bought it. then i have changed oil for Mobil S semi synthetic, becouse previous owner has been used semi synthetic but he do not know witch becouse garrage just to do that for him. Car has done 146000 miles so far. I have no clue how the car has been used before. What sort of oil are You recomend for my engine?? What do U think about Valvoline Max Life 10w 40, will be ok for turbo engines??
cheers

 

that engine has hydralic tappets...

try a fully synthetic

 

Tapping or knocking? With 146k on the clock i would expect a little more noise from the lifters however the above knocking and tapping are quite different.

First of as suggested change to a fully synthetic i would go with a 10/60 millers.

 

Thanks guys!
What brand are U recomend, MOTUL will be fine ?? Let say
MOTUL 15W 50, 300V Competition ??
Is it safe to go down from semi-synthetic to fully synthetic?? Becouse I though is no so good.
regards
Greg

AAAA sorry You recomend Millers 15w 60?? so will it be safe to go down for semi synthetic??
cheers

 

fully synthetic is better than semi-synthetic

 

yeah fully syn.. I like motul 15w50 300v.. others prefer millers etc..

 

Agree with jolly on that, or silkolene, mobil seems to make any engine noisy, especially top end!

 

Thanks for all help!
I will immediately change oil for Motu 15w 50, or millers 10w 60
cheers
