Quick question, can over filling oil in your rotary cause lack of power when you put it on heavy load?? also not redlining?

 

How much over fill? Most people don't put in enough to begin with.

 

well... when i check it, it's over the high point on the dipstick... but i thot it wouldn't matter that much.. considering it eats it anyway... any thoughts? maybe the oil pressure is messed up and i'm losing power?? i dunno i'm just shootin bull i'm new at this

 

do an oil change haynes says 6.1 qrts with filter change..... oh **** i only put 5 in mine thanks for making me look that up lol

 

oh really? i'll remember that now!

 

putting 5 quarts in generally does the trick because you can't get the last 1.1 quarts out of the oil cooler.

 

so is over filling the cause of my lack of power?? or could it be somethign else?

 

no overfilling is not going to cause a loss of power. there is no "crankcase" per say in a rotary so there is nothing sloshing in the oil in the pan.

 

I don't think overfilling the oil could cause a loss of power, but you're going to do yourself some damage if you filled it enough that your oil pressure get too high. Luckily, you have a gauge for that, so check it.

 

yeah, it seems fine, teh oil pressure... why am i losing power ? i can't redline either. It was fine before I replaced the radiator... unless... i effed up and it overheated... QQ

 

Okay, where exactly are you losing power? Is it just not making power like it should, or does it feel like you're hitting a brick wall at certain RPMs?

 

i hit a brick wall at like 6-7 rpms, and just won't go past it. I have an exhaust leak if that does anything??

 

Cats clogged?

My friends 12a wouldnt go past 6k we did the water trick and now it'll hit redline roughly.

 

what's teh water trick??

 

There's a lot of misinformation here.

First, oil level does not have anything to do with oil pressure. As long as the pump can pick up oil, the pressure will be set by the speed of the engine and the oil pressure regulator.

Second, nothing horrible will happen if you overfill the engine. Since there isn't an issue with windage in the rotary, a bit more oil is not an issue. I generally over fill by about a quart so I don't have to add oil between changes.

Third, you can end up frothing up the oil with the oil pump drive chain if you overfill. Usually this isn't much of an issue since the pickup is at the bottom of the pan.

 

oh that makes sense... any ideas on why loss of power? if it over heated slightly would that be my main concern ?

 

Clogged cats was already mentioned.

What happens when you loose power? You need to be very specific regarding the symptoms.
