Would a dent in the oil pan cause oil to not get to the upper engine? This is what the Tech at my local Mitsubishi dealer is telling me why my lifters are knocking off and on they will knock for a couple of days and not knock for 2 weeks or more. He is saying there is a dent in my oil pan. My wife nor I have hit anything, the oil has been changed at proper intervals with the correct oil, and we just drove from VA to TX back in April with none of the above problems. When I had the oil changed, twice in a month, none of the Techs mentioned this and one was even at another Mitsubishi dealer that I took the problem too and it still made the knocking, but I was unable to leave it there because I didn't have a ride and they didn't do loaners and they said they would have to take the engine apart to see if it was oil starved (on my fault) or to see what the problem was. What can or should I do? Should I pay the $630.00 or take it else where. I am a Universal Technical Student, should I take one of my instructors with me to see this problem? Any help would be appreciated. Thanks for your time.

If you show oil pressure, the dent shouldn't bet the problem with getting it to the top. If you are getting oil pressure, the lower end is getting pressure. The top should get it too. The only thing I can think of is if there isn't enough oil to the pump. I would think that would show on the oil gauge. In my mind, the oil pump doesn't determine where the oil goes. A dent wouldn't tell the pump only to send it to the bottom end of the engine.

If there is any iol starcation, the oil indicator light would come on.

It is a known prblem with Mitsubishi engines that the hydraulic lash adjusters (HLA or commonly called lifters) tends to knock intermittently. Some of the HLA are not functioning correctly and you can either replace them or have them serviced/cleaned to resolve the noise.

One of the main cause of this problem is oil condition and quality. Engines that have sludge accumulation due to whatever reasons would more likely have this problem.
