7MGE oil pressure

Arne (Denmark) · 05-30-2007, 10:37 PM

BTW.

When the car idles it sounds like a new engine. No knocking at all. Only when you accelerate the engine makes a rattle and I suspect that one ore more valvelifters might not be opening. I've heard this before on other cars and they can make a terrible noise.
I topped up the oil with some thinner oil and now the problem arose. I will change the oil to see whether this helps and check the cylinder head/valve lifters to see for damage.
I have found that the pressure is actually "ok" for the oil. It is supposed to be 0.3kg/cm2 or more once idling. 2.5-5 kg/cm2 at about 3000rpm.

Am I right. If it was one or more bearings the car would knock once idling as well?
All just assumptions but you guys must know how nervous a person gets once your baby is sick :-)
I hope for the best. The engine is otherwise so smooth and cultivated...
