Ishihara-Johnson Crank Scraper Product Review
So, now that I have installed my crank scraper on my new engine I thought I would go ahead and write down some installation notes and some impressions.
I bought the Teflon version that has a Teflon insert that you cut to fit your particular crank.
In my case the metal portion of the scraper did not have to be modified to fit. The suggested clearance was more than adequate for all parts on the metal part of the scraper I was sent.
As for the Teflon part, I cut mine with an exacto knife while my engine was on a stand. I completely bolted everything up, including all the nuts that hold the insert in the crank scraper (two pieces), and cut it that way being careful to have the Teflon land on the floor and not in the engine. If you don't do this your cutting won't be very accurate. I am not sure how well a dremel or anything else would work. I suggest you use a new sharp exacto and be careful while cutting. I didn't end up with a perfect "fit" but I think I got it close enough. I ran out of steam as it took me at least an hour and a half to cut, and I was in a fairly comfortable position with the crank directly in front of me while I sat on a stool.
If you are buying this with the engine in the car I wouldn't even attempt to cut the teflon scraper to be honest. I'd just get the regular scraper. I don't see how you would have the energy for it. If you are on your back it would basically be impossible. Even over your head on a lift would be more work that I would want to fathom.
Last, if you buy the teflon version I went ahead and blue loctited my nuts on. Not sure if it was necessary, but it was on the bench and I figured it was best to make sure I didn't have little nuts flying around my oil. Also, if you buy the teflon one, there are two *small* washers per stud on the scraper, so be careful not to lose those.
I'll see if I can get a picture of it installed tomorrow.

Ah. Mine was built not that long ago, maybe a month or two ago. I actually just met Kevin about 2 hours ago. Long story, but he sent me a reinforcement bracket for my pickup tube and I had one of my old addresses in paypal. Need to get engine together, must go to welder soon, sebring coming up, wanted to have dinner with parents....
If you catch this, pop over to my other thread if you have a chance chris. I'd like to hear your thoughts on the pickup tube discussion that started in my lindsey baffle thread.

I just finished fitting mine. I'd say I spent 4 hours getting it to clear the pan. It could be done in less if you are mentally prepared in advance. Get comfortable with the idea of going to town on your shiny new piece with a grinder, dremel and shears. At least if you are running a late model oil pan. Good luck!
