Black Engine Oil

[Trust33]

Compression or leakdown will confirm if its a problem with blowby.

Indeed.

I also wouldnt be worried.My oil comes out black and it doesnt take it long to do so.

When i bought my car it blew black smoke on 7psi with the stock computer and a 3.5'' catback exh with pod.But with the pfc,12psi will occasionally puff black smoke @ 182rwkw.Thanks to jim's tuning at CRD.

Like morgs said,if your worried about the smoke do a leakdown test to determine whether or not you actually have a cylinder pressure issue.And hopfully it will help to shed some light on the situation.

After talking with Eli and a number of others, we are going to leave it in there for another couple of weeks, dump the oil and replace it and the filter and monitor it for a week..

reason for leaving it is that if it is in fact sludge buildup it will hopefully get all of it free - suspended in the oil and get rid of most of it in 1 go..

I will also be switching to Motul as most people on here recommend..

i do realise people say my oil is fine.. but I don't like the fact that in the space of 4 days - i've completely saturated it with carbon..

cleaning it out is a good start rather than leaving it in there for more to build up or overcome it's suspension properties..

After eduacting myself in the past 2 days - I think there shouldn't be any issues.. when I get it serviced next i'll probably get a comression test done and this should give me an indication of any piston issues..

i'll keep everyone posted..

As for the A/F ratios - i'm thinking about looking at a SAFCII + R34 GT-T intercooler for the summer as I know how hot it gets..

For the popping issue - I think maybe a Split 3" dump pipe might help resolve this issue..
