(i know this is a all motor area....but this should quaulify...)
JUST TODAY i drove my 95 GSR/B20b turbo its virgin total of 20 miles and then took the oil pan off to make sure everything was good in the oil itself....IT WAS NOT...i have pieces....small but still noticible pieces of my bearings in the oil...who knows how mych may be in the filter... the ideot that built the motor told me that he used a set of bearings but they were slightly larger and if i use a THICKER oil, everything should be just fine....im pretty sure he is WAY WRONG now that i pulled off my oil pan...any ideas on what i should do?

 

Flush you engine, pull your crank and check for damage, if there is no scarring on the journals, replace with the correct size oem main and rod bearings.

 

how do you know it was bearing material?

 

thats what the mechanic said that it was...

so basicly ur saying that i might have to DIS-ASSEMBLE the ENTIRE bottom end?...i dont know if this is important but my B20 crank was pollished also i think...so would that effect anything???

 

Youre saying that the guy who built your motor said he used larger bearings than he was supposed to and that you should use thicker oil to compensate??
****...what a joke...

You should make him redo the entire bottom end for doing something like that. Or better yet get your money back and have someone who knows what theyre doing rebuild it.

yea dude...i payed him $360 to build my bottom end and he told me there was some play with the bearings and i should use thicker oil to help make up the difference...

 

Wow, definitly not good at all. Any idea on how big of a clearance difference we're talking about?

 

no not really un lucky for me i never really got too into the whole cm/mm stuff... just the know how and what to get and have put together.

 

You should find out if he knew then, did he say WHY he used a larger bearing? Something isn't adding up here. Also was it metal chunks or just little pieces that look like glitter or sparkly oil? That is normal for a fresh engine getting all the assembly lube out and breaking in everything else. If the metal pieces are "feelable" grainy metal pieces that is not normal. Was there any wierd noises?

 

i think his reasoning was that he said that the crank was prolly pollished too much or something...im not too sure...he said there like stock B20 bearings but for some reason they just didnt sit right....what would be a reason that a lazy *** engin builder would use bearings with a slightly larger clearence...? and naw no wierd noises...the peices were very small chunky peices...bigger then glitter sizes...and yea you can most def. feel the peices....

I hear horror stories every day because there a lot of engine assemblers out there posing as engine builders. If he knew there was a clearance problem, he should have found the correct bearing, they are available. You said your crank had to be polished, was the block line bored? One post was to get the correct "oem" bearing, I would use ACL Coated Bearings instead. That would at least have given some protection from someone not providing the correct bearing clearances.

everything that the machine shop recommended that i do was done prior to asembly...honed ...balanced....every thing that you should do...i did... now you mentioned ACL Bearings...where can i get them and if i need bearings with the RIGHT clearences...where can i find those....web site? phone number? shop number? cause i will have someone do the proper measurements needed to scale for the right stuff... but i really need to know where to get it from so there wont be a lack of rescources issue holding up the completion of the motor...thx u guys i really appreciate all this...

I used ACL's in mine 'ONLY' because they gave me the right clearnace I wanted for my setup. You should really have it plastiaguged to find the optimal clearance for you're setup.

 

Aw geez man, you just can't catch a break, I saw the thing in the FI forum. Try not to get too discouraged, Your setup will be sweet when finished right.

Good luck

 

What was the ID of the big end of the connecting rods you are using.

 

I don't think he knows, someone built it for him, I asked about specs on it too.

 

well, you can get the ACL's at http://www.kteller.com for a good price. If you dont know the specs and the mechanic doesn't know the specs (not that I would trust anything he said anyway), I sorry to say that your motor needs to be taken down and checked before you can do much. You may be able to slip in an ACl set and plastigauge it in the car but odds are that you need to have the crank polished again. Sorry about the bum luck.

 

I would have your motor rebuilt by Hybrid Perf. in Bakersfield. 99Hybrid_Hatch is the owner/engine builder there.

as for any specs....dude i have no clues...sorry...just know my set up consists of the following...Scat Pistons 9:1 / Eagle H beam rods (forged) / ARP rod bolts / B20 block guard / stock B20 crank lightened and pollished / excedy street & strip clutch / fidanza alu. flywheel (7.3 lbs) / 96 LS tranny...and some other stuff i cant remember right now...

 

bump for any ideas...

 

I can hook you upwith ACL CT-1 Coated Engine Bearings. Contact me at 704-483-2202 X-1111 or dadams@calicocoatings.com.

 

gsr_b20x2 hurry up man...i need my stuff from ebay. i havent recieved anything yet and you're not noting me back.

 

What was your oil pressure like? Did you hear the engine knocking?

I've actually heard of people increasing the clearences to allow more oil to hit the crank, I have never heard of increasing the oil thickness... maybe we're talking about two seperate things?
