Crank Scraper (review)

[JGood]

I really wasn't impressed with the craftsmanship of the scraper. I had to enlarge/elongate several oil pan bolt holes in the scraper, this should not be a requirement of installation, bolt holes don't change from block to block. Also the fact that it took a month with crappy communication to get it shipped to me. It's too bad there aren't other suppliers out there.

Wow, sorry to hear you had bad communication. I emailed him, he responded a few days later with a phone call and email, and had it made/shipped out a week later (although I did stress my urgency).

I did find that some of the bolt holes were off and the fitment wasn't perfect, but I'm far from an expert when it comes to this kind of stuff so I'm not sure what kind of manufacturing variances to expect. I'd think since people swap cranks and oil pans and stuff all the time, and the tolerances for those have to be damn near perfect, that the scraper could have better tolerances... But I was OK with doing a little work on it.

Another issue for me was the oil pump. The area where the oil pump seals against the block wasn't large enough for my oil pump. I had to remove quite a bit of material to get the oil pump to sit properly with the scraper. For those of you who plan on using this scraper, MAKE SURE YOU INCLUDE THE OIL PUMP DURING THE FITTING/GRINDING PHASE! I had to go back and clean off the RTV I laid down in order to do more grinding. Total pain in the ass, but could have been avoided if I thought to check the oil pump clearance..

Just installed mine last night.

I had to do the same exact thing. RTV sealant and all. I actually took it off and rushed to cut the hole bigger and slapped it back on while the RTV wasn't set yet. It will probably leak and I'll get to do the job again in the car.

Yeah, must be my ISP. I'm at work now and can access it fine. I can also access it via my iPhone on the cell network, but not when I'm connected to my home network.

I sent them an email to place an order. Looks like a nice product!

Nope, getting "Page not found".

Weird, must be an issue your ISP's DNS.

Not sure which one you were wanting info on but here is the info for the M20 version.

NEW! The M20 pattern is now a dual-scraper -- the added blade operates on the downstroke and shunts the oil to the side of the pan. M20 (L6): 2.0, 2.3, 2.5, 2.7 $89.95 [steel]; $189.95 [Teflon®]

I have one on my car, but it is hard to say where the results are coming from as I have an accusump, a very large oil cooler a remote mount oil filter and carry about 13Q of oil. So much oil in fact that I need an oil heater on the car to pre heat the oil before starting motor. With that said I am glad I have the scraper and would do it again

Bump

Where are the crank scrapers available from? www.crank-scrapers.com is not working, which from previous threads seems to be where people were getting these from.

If you could work M30 scrapers into the GB, I'd be in.

Sorry Brian, I know zero about crank scrapers for the m30, only baffles for the m20. Good luck!

That's good to know, I had been wondering if these were worth the money. Thanks for following up!

My buddy Wes Hill is the guy that designed these for the Pro3 Group. I spoke with him today about a second run of the baffles. I wonder if there is enough intrest out there for a group buy?

I'm installing my second one in ten days next Wednesday. It will be the fifth one I've done in a year and a half. I'll shoot some pictures of the baffle and the install in the pan and post a group buy feeler with pictures.

this is not Internet bs.....I have one too. IT JUST FLAT WORKS. I was seeing under 10 lbs on a short hard lt hander over and over.......but now?...over 50.

There are around 40 pro3 cars that use this baffle with zero oil pressure issues. I previously had a custom fabricated pan with a trap door, along with an accusump and was having pressure issues. I switched to a stock pan with the baffle installed and never see under 50 psi on track, monitored with my AIM system. The baffle just flat works. I reccomend it for anyone who tracks or races their m20. My two cents...

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.
