hairline cracks in back of block? fixable?
 

Hey i found hairline cracks *around* the oil feed line thing and *around * the oil filter thing its on the block but around these 2 things... i'm thinking this is the cause of my oil leaks? maybe? also would JB weld fix this? let me know!

i don't have it anymore hotrex so quiet now!

Re:hairline cracks in back of block? fixable?
 

i noticed it was gone, judging by the 90 degreee bend you made from 2 pieces of straight pipe :-X

Re:hairline cracks in back of block? fixable?
 

no that wasn't it... its gone, threw it away.. along with the rest of your "chargepipes" you gave me

Re:hairline cracks in back of block? fixable?
 

You sure its just not imperfections in the casting? They sometimes look like cracks. The oil leaks are probably comming from the oil lines and not the block but this is only a guess cause you didn't post pics or anything

Re:hairline cracks in back of block? fixable?
 

Yea i agree with whitey... very unlikely your actual block is leaking... u may be drippin above

Re:hairline cracks in back of block? fixable?
 

okay i post saying whats up.... this is what i KNOW

-NO leaks from oil feed line
-NO leaks from headgasket
-NO leaks from intake mani gasket
-NO leaks from PCV valve
-NO leaks from oil sending unit
-NO leaks from oil filter

*possible leaks*

hair-line cracks by:
-oil feed line
-oil sending unit
-oil breather chamber
-oil filter
ALL ON THE BLOCK, some worse the others, can feel all cracks though.

1 more possible leak:

-oil breather chamber o-ring


**FEW IMPORTANT FACTORS**

-ONLY leaks when warmed up
-leaks more at more throttle
-Oil ONLY drips under where the oil filter is, makes kinda a "U" shape and drips down to the oil pan and drip drip drip..
-NO oil running down block above the oil feed line.. so nothing leaking above
-Could loose 1 quart of oil in about 1 hour *guessing*

let me know what you guys think.. i'm stumped besides the hair-line cracks i found just today

sounds like the oil breather box.

Re:hairline cracks in back of block? fixable?
 

are you actually being serious now hotrex? also people said it could be that but then they say it can't be cuz it shouldn't loose that much oil... 1 quart in about an hour.. thats a lot...
