I am curious if a standard crank scraper will fit on my 2.3 stroker? 4G63 block w/ 64 crank.

Im thinking of getting the cosworth scraper.

 

it will need to be clearanced if you are using a 100mm stroke. 60thou minimum

 

And how would I clearance it? Just add some spacers between the scraper and the crank girdle?

 

buy a dremel, buy a carbide cutter & use that to make room for the rods / crank throws.

 

or you could trial fit it and bend it downwards to clear the rods/crank

 

Thread resurrection... will be installing an AMS/Moroso extra-capacity wet sump oil pan soon, and it includes a crank scraper. I'm using a Manley 100mm billet stroker crank (#190120B).

Roughly how much clearance is enough? Half a millimeter? A full millimeter, to be 100% sure nothing will hit?

Thanks in advance!

 

.060" on everything. It takes a while to check and you'll need the engine fully assembled to how it will be running as the crank counter weights and rods end will hit the scraper.

 

Cool, so about 1.5mm... got it.

No problem; I'm installing the AMS pan after the fact, on an already running/installed engine. There will be lots of staring upwards from under the car and oil dripping into my eyes, though, probably.

 

I bolted mine on the best I could and rotated the engine until something touched and then marked the area with a Sharpie then rotated the other way and did the same. This took about 10 times to get everything cleared.

 

I had to modify my AMS scraper that came with the sump to clear the 4g64 crank.

Where you have the 90degree angles on each section for the rods to pass i ended up cutting them at a 45 degree to clear the rod bolts then as alreasy said used a dremel to get clearance.

 

Has anyone see an scrapper that fits the 4G64 block???

Nope. I had to modify the Cosworth one to fit my 4G64

 

In my hunt for a crank scraper for a 4g64 i found this has anyopne dealt with him before, or heard any feedback.

Is that recommended? Using a used crankshaft?
I am about to build my engine, and my "guy" told me that using a broken-in, used, crankshaft from another Mitsubishi car was going to be better, as supposed to getting a new one.
Anyone has inputs on this?

 

I had them do a crank scraper BACK in the days for me for my 3sgte mr2 turbo. They have been around for a while I see. Anyhow, that crank scraper they made for me worked like a champ.
