Big Ends R32 Rb26dett

could it be a dirty lifter?

guy i was talking to at a work shop thinks it will be just that....

and a oild change and filter should fix it.... sounds to good to be true

but i did start it today cold and it had the rattle then... after a couple of seconds went away and wouldnt do it till i slowly held the throttle till it got up to around 3500 4000rpm? befor it had the rattle again.....

Definately big end, and the oil pump is probably stuffed too. PS rb26's dont have hydraulic lifters, i would go to a different mechanic who knows rb's

good point about the oil pump - thats what worries me about just swapping bearings. where is the bearing material that has come loose? in the oil pump? in an oil gallery? in the turbo oil feed? in the oil filter block/cooler? in another bearing?

If you've spun a bearing, disassemble and clean the whole motor

its getting looked at tomorrow its getting a flush and oil change and filter... keep you posted

[PHA71L]

if it is a bearing it will be getting pulled out and fully cleaned ect

If you can rev it to 4000, the brg hasn't turned in the rod yet

motor is coming out hmmmm......let you know what we find when we open her up

[PHA71L]

its all out now... so far its looking like its just starting to spin the big end on number 6 it went in today to get looked at rebuilt ect.....

im going to do the clutch while its out and machine the fly wheel... just to be safe, has a few hot spots and is a little worn...save pulling it out later on

also only has the stock dump pipes on the stock turbos are they worth changing? didnt look to bad for stock i thought....if so who make bolt on replace ment ones?

and what kind of head gaskit should i run?

how good are stock ones for?

it has had a bigger metal one in it...it has cp pistions rods ect all ready, do the cp pistions raise the comp at all? thanks in advance steve
