I've heard some folks say to use brake cleaner to cleanup some oil mess on the motor. Well, I have a leak on the top of mine somewhere(just replaced my OMP lines). Since doing the lines, my car smokes like crazy(never did before) and eating about a quart of oil every two days.. Would it be possible for the oil to be leaking down the side of the motor or into the intake and getting burned up in there causing the smoke?. I have some oil buildup on the top of my housings. So I just wanna be able to clean the **** off without yanking a bunch of crap out if possible so I can see where it is leaking from. Will the brake fluid hurt my car in any way(engine wise or any other component I can use to spray in the engine bay)? I've done the searches for where the leaks could be, but I don't think that my engines oil seals are shot. Thanks in advance for the responses, any help would be appreciated.

If it's been burning a crap load of oil SINCE REPLACING YOUR OMP LINES I'd suspect that you may have accidentally altered the flow rate of the metering pump so that it's getting way too much oil.

The position of the washers on the bottom end of the actuating rod from the omp may no longer be in the right place. To confirm proper oil flow, do the following experiment:

Undo the metering lines from the carb end and place a metered container (like a measuring cup that reads in cubic centimeters) under them to catch the flow. Get another container with engine oil in it to dribble into the carb at regular intervals during the test. Now start the car and have someone hold the revs at 2000 rpm for exactly two minutes while you dribble a little oil directly into the primaries every 20 seconds or so to keep the apex seals lubed while the lines are unhooked. During this time oil will be dripping from the metering lines into the measuring cup. After two minutes shut the car off and measure the contents of the measuring cup. There should be 6 cc's or thereabouts of oil in it, give or take one. If there's much more than say, 8 cc's that may explain the excessive oil consumption and smoke.

The only other thing that causes oil consumption in these engines is worn galley seals leaking from between the housings on the drivers side near the top of the engine (not serious, just messy and annoying) or worn oil 0-rings on each side of the rotors, which is a rebuild issue.

As for the oil on the outside of the engine, simply spraying the engine bay down with Gunk or similar engine degreaser and then spraying down with water does wonders. You may have to repeat the process if the engine is particularly grimy.

Hey ! Watch it, Bud.

Be careful with brake fluid ! I think you meant brake cleaner, but instead listen to Aviator and use an engine degreaser. It's alot more effective and gentle on the paint and rubber at the same time.

thanks for the quick responses guys. I'll measure it in the mornin'....Now I need to find the measuring device you were talking about. Where can I get a measuring cup like that? Hardware store? Would O'Reilly's carry that you think?

I got my CC Container for free from a drug store.
Just tell them you need something to measure baby medicine dosage.

I find it hard to believe that an omp would consume a quart of oil every other day under daily driving conditions unless it has a severe leak. I added some extra washers to my pumps linkage one time for kicks and giggles to bump up the flow and still never noticed any smoking or excess oil consumption.

Aviator 902S

No, but combined with leaking galley seals and questionable o-rings a quart of oil could disappear quite quickly.

Of course, there's one other possibility--- if new o-rings were installed onto the sides of the rotors, but the side housings weren't lapped and nitrided these o-rings would wear out very quickly, resulting in a cloud of blue smoke in tow even after warm-up. Was the omp work done at the same time as the engine rebuild?

Well that's kinda wrong. I installed new o-rings in my oil seals and did not lap the plates. No smoking problem at all. I think you meant to say oil seals and not o-rings.

I set my OMP lever to the 9 o'clock position when I didn't have a rod and it didn't smoke at idle.

Aviator 902S

As long as the plates are within limits the oil seals (yeah, I know they're called oil seals, but technically they are o-rings that fit inside their respective cases) shouldn't wear out. But if the plates are worn to the point where there are some serious edges that can be snagged with a fingernail the seals won't last.

Yep. My plates have a little step wear in the usual area near the spark plugs, but the oil seal track was ok. The oil seal wear was pretty much right at spec. I threw in some Atkins Viton o-rings and that engine doesn't smoke at startup or at any other time anymore. I have another set of plates with similar amounts of step and oil seal wear and I hope to get lucky twice.

well, it's weird....My engine smokes when I rev it, which according to the search is a seal issue more than likely. But I thought it would be a progressive thing. I replaced the oil line the goes the the beehive cooler(hardline from the oil pan/engine area) and the OMP lines. Since then, the car started to smoke...I wanna try and figure it out for sure before I do my 13bt swap.

Been quite a while since I posted this, lol....Since this incident, I noticed a pool on the passenger side of my motor which appears to be coming from my OMP. The pump is all grimey looking. I'll pick up the degreaser in the morning as well. The police academy has kept me tied up lately. I just noticed the pile of grime during the first phase of the rat's nest removal(write up by Rx7Carl). I have new crush washers for both sides of the banjo bolt on the BeeHive cooler, new o rings for the underside of the beehive, new oil pan gasket, oil pan drain plug and crush washer, and some new belts. Hopefully I can find the issue. Reading through the search on "too much oil omp" I found 10 pages to read through. My pump may need a rebuild which I will do since it doesn't cost much. If it still acts up(the OMP), then I'll block it of and premix. Anyone have the number to Lowe's?

crazy smoking that appears suddenly could also be cause you put too much oil in the "crankcase" (what the **** am i supposed to call it? someone help here)

there isnt enough room inside the engine for 7-8 litres of oil, and oil will be in the fill tube... then it gets sucked into the PCV system (positive CRANKCASE ventilation? doesnt apply again) and smokes like a ************.
