Oil In Head = Big End Bearing

[ripps]

just wondering how many of you out there this has happened to and how much damage you have done. the story goes first day at the track (haunted hills hill climb) get a good couple of pratice laps in then what we think at this point in time and after reading its a big end bearing wont know until we pull the engine out but yeah were pretty sure it has got oil in the head and run out of oil down the bottom from the car and the movement on the track and high revs. just wondering what you have done and what sumps everyone has used. i will be puttin one of those things on the back of the head to get the oil out but just wondering the best sump and where you have got them from and sort of price. also is the rev limiter bein set at 8 and a half to much revs

thanks

I think it's the severe lack of punctuation.

It's hard to help you out when no one understands what you're asking.

sigh... no detail = fail.

what motor?

what mods?

also, you dont need external oil drain from the head. waste of time.

ill ask even though i probably know the answer...

did you overfill the sump by 1L like you should have?

Bingo bingo and bingo.

I went to all the trouble of doing the rear drain on cats car then tested it on the dyno..... even with it disconnected and running 7500 for close to 15sec (don't recommend this unless you own it ) is still stayed dry...

its a rb26 r32gtr with 330 kws,660 injectors, 3 and a half inch exhaust, acl bearings, cp pistons, ported and flowed head, n1 oil pump, and no it wasnt over filled by a litre

[ripps]

also would like to put a bigger sump on any recommendations

[R31Nismoid]

Well that’s your first problem. A big no-no.

acl bearings, cp pistons, ported and flowed head, n1 oil pump

This sounds like the second…

What oil control/restriction mods were done as a part of the rebuild?

I’m gonna take another ‘wild’ guess and say none?

Realistically you don't need a sump if you've done everything else correctly for that level of setup.

Plenty of people before you have been totally fine.

So the head to sump oil return line that people have been using for years and everyone always says to do it.... Is a total waste of time and money and dosent make any benefit what so ever??

Not one circuit GTR down here has one.

If everything is done right with block restrictions and so forth, then you don't need it.

If you did a list of people with them, and then without... it would be extremely one sided.

not everyone, just everyone that only reads one side to the oil control in RB thread

and not to say it doesnt work, just doesnt work the way people think it does

but the ones trying to disprove its function only claim how it works in what they have seen on the dyno

how can it be tested on a dyno when it is not subject to the same g forces being placed on the car like it would be if it was at the track

that and the fact that they dont use them and dont have issues,

maybe there should be one at the front of the head, so under heavy breaking all the oil rushes into the sump
