Crank Scraper (review)

[RangerGress]

didn't you already install the scraper + accusump?

Yes, but the oil pressure data I collect should still be valid. Jon Allen's oil pressure data was collected with a scraper, and my Accusump checkvalve isolates pump OP from galley OP.

I'm still working on calibrating my pump OP sensor and the Traqmate. The data I collected this past weekend at Roebling was no slam dunk in support of Jon's data. I've tweaked the calibration a bit more and we'll see what it looks like at Road Atlanta.

Bringing this thread back to life because I'm interested in the baffle. New information has surfaced in the past yr because a guy connected an oil pressure sensor to his data logger. He found that his pump was sucking air on all left turns and many right turns. He was running an I-J crankscraper. One guy's experience isn't conclusive, but it's interesting.

This weekend is the first time out with a OP sensor connected to my data logger. Once it's calibrated, that will be another data point.

Up above a guy mentioned that E30's are raced with few oiling problems. I would disagree. We go thru a lot of bearings. I've done it twice. Now I run an Accusump.

Excuse MY ignorance, but what is the intention of a piece like this?

to reduce press drops..esp on lt handers...mainly for track work.

bumping this thread as i plan on doing this on the track car over the winter. mspiegle, any issues with the scraper so far? i'll probably go with teflon to reduce install hassle. planning to do in my garage, along with timing belt, water pump, thermostat, fan delete etc etc. jrk, wanna come help?

edit: any thoughts on accusump vs the scraper?

Easiest way to remove oil pan in the car is to unfasten engine monts and lift the engine up 2". The way my friend did it, was to support engine with the hoist and drop subframe (it moves about 4 inches this way). If I was to do this again, I would do what my friend did, was much easier aligning gasket and more space to move thing around. Let us know about how the scraper holds up and if you see any difference in a long run.

Excuse my ignorance, but where do you get a baffle like this?? Wow I want one!

pm me......

ya..my engine wil be in car.....

but no fitting for me. ...Im going w/ the item shown in my other post.

Oh, gotcha. As long as you can pull your oil pan out, I don't see why that'd be hard at all.

great initial thoughts thanks!!!!!!!

...any insight on how a newbie like myself( I just do brakes/tune ups) can get the oil pan off myself...w/ the car on 4 jackstands....Id love to save the labor costs on this one. Ive been quoted like 3-4 hrs by shops....thats like 350 in my neck of the woods!

It's difficult for me to say because I've never removed an oil pan with the engine in the car. I would imagine that if you were able to remove the oil pan and the oil pump, then your main issues to contend with would be the fitting-phase. You'll need to turn the crank quite a bit (by hand) and have lots of light to look for all the clearance issues. You'll also want a bunch of washers so you can secure the crank scraper against the face of the oil pan rail during fitting. It would probably also help if you were able to lift the engine up a few inches to get some extra room to work. It's probably doable... but not very fun.

Yeah, the one thing I wasn't clear on is whether the steel base in the teflon system was actually cut with more clearance (so that you only need to slice the teflon with a knife).

the way it was 'splained to me was that only the teflon needed a bit of trimming and it was ok if it rubbed a bit!..so it was a quicker install.

I sent you a pm!

GG..Ishi had expalined to me due to BMW varying castings there was no way to make a one size fits all......and keep close tolerances.

Actually there is - It's called engineering. - but just not at an e30 price - just to clarify.
