Bits of Metal in rb20 sump

Recommended Posts

So, i pulled the sump off my rb20 today to redo the gasket and have a suss for internal damage and came across this (picture below) resting in the bottom of the sump and i cant figure out what it is and if i should be overly worried etc

i have no idea if its a stock engine or not. no real history on it.

 

going by the rest of the dodgey shit the car came with im going to assume the worst..

 

how would i go about investigating piston/general engine type etc. and how to check the big end bearings

sorry missed that part. flip the engine over if its on a stand and take bearing caps off. get pics of the base of pistons also. see if there is any other damage.

time to pull it out and put it on a stand for a closer look.

best...someone didnt clean out the sump when their engine blew up (unlikely)

worst... i think you know the answer to that one

it also looks pretty chewed up too.. there might be some crank/piston/rod damage.

 

i think its fairly safe to say you got two options here....

 

1. clean motor up. do quick check of bearings and anything for damage.. nothing else damsged then put another squirter in. check for piston clearances. if all good then put sump back on, fill with oil and prey that it works.

 

2. scrap or rebuild it

Remove it. Block the hole. Thrash it. If it lasts it's a bonus ;)

its only an rb20. they give them away free with every pod filter sold at autobarn

nah no stress leave it as is, the transfer hole is the same size as the outlet hole so its not doing any harm how its sits now, only issues is poor angling of oil spray... not really an issue.

 

just checked no1 and 6 bearings and they got simons nod of approval,

 

so im safe to leave it? no need to remove and block it? just dont want it to go POP on the track

If you can't afford to blow up the motor, why not do it properly the first time?

if i didnt want to do it right the first time i wouldnt have bothered to drop the sump and sift through oil for half an hour looking for metal such as this. from what i read its ok just to block up the hole (however im still skeptical), which is why im asking all these questions regarding how safe it would be to a) just leave it or b] put a new one in there or c) take it out and block it.

Well if you want to do it right, remove motor, refresh and fit replacement oil squirter, refit motor. That would be doing it right.

believe it or not but its a common problem on an rb20 to smash the cyl1 or 6 oil squirter from the piston hitting it..

 

seen it twice now, both motors had 20psi oil pressure tops. and the bearings were worn but still 'intact'. dont know if its a bearing problem or a bent crank thing.

 

i just replaced the bearings, put a new oil squiter in and it fixed the problem.

 

i got oil squirters around here if u need any
