ok so i open my ls motor today to see what kind of bearing it have it turn out all the rod have green bearing this is on ealge rod and the main are black brown green brown green i know acl bearing has the same spec with honda green but what about the main bearing can i put acl bearing and platicgauge it if it out of spec then use oem bearing for that jornal ? please help me out first time buiding a motor ....

does any one know what kind of block guard is this their a t o p f on the top size and b 16 18 on the bottom


should i even run block guard ?

 

pretty sure ACLs only come in one size... plasticgauge the bearings to double check that they will be good...


no, dont run that block guard...

 

should i use race or std bearing from acl i hear race one have bigger oil hole coating and more clearance then standard one how come it not a good ideal to run that block guard ? create hot spot ?

 

I would suggest buying bearings from honda, its a little more expensive, I went that route so I know I wont have any problems. if it is off a little you can just swap half a bearing for the size difference you are looking for and you should be set. which didnt make much sense to me but the size incraments are so tiny, motor shops and old guy machinists all tell me thats acceptable.

 

Yes, block guards do create hot spots and aren't a smart thing to run. Do a little research and I don't think they're are many knowledgable people out there anymore suggesting to use them (if there ever were).

 

ACL's standard size is supposed to be like a green bearing, but they seem to be a hair closer to the brown's lately. And since your journal sizes are kinda all over, probably better off just getting the according honda sizes and plasti-gauging them anyway.

 

acl comes in different sizes.

I've been running a blockgaurd for so many years now, I sleep better knowing its there, I just spun a bearing should I blame the blockgaurd for that?

 

really? i didnt know acl have diffrent sizes but does anyone know who made that block guard ? look like KMS to me .... i doubt that i put the guard back in the water hole is way too small i think... well any more tip on wich bearing to used please let me know ...
thank

 

if you are gonna use a blockgaurd use a golden eagle or str
my block with golden eagle gaurd
