Oil getting into number 1 cyclinder & what clutch?

[craigcorish]

Hi all I have an Evo 4 at 320bhp.

Recently its been using quite a bit of oil and gives off whitey/blue smoke under power, and you can smell burning oil. So I went to check compression and got close to 5 bar per cylinder, how ever my battery isn't too clever so these results won't be right. Anyway as I had the spark plugs out I had a look in to the bores and noticed that number 1 cylinder had oil in, so I cranked the engine and it went away and then I watched to see if it came back and it did, within 15 seconds the cylinder had a pool of oil again (Bear in mind engine is off so I can I rule rings out?) Just wondering if anyone has seen/had this problem and what was the cause?

Obviously I will be removing the head, so would need head gasket and bolts, at 320bhp (I want around 360 soon) would a standard head gasket cope? and standard bolts?

Another question I'm in need of a clutch, but as I only fancy 360bhp, 370 max what clutch is good enough at a reasonable cost?

One more quick question I've bought a TD05HR 16G 10.5T will I benefit any power installing this?

Thanks

A lot of questions there....
Bigger 10.5 turbo will benefit you
Oil leak could be valve seals
You will be very lucky to get 360 from a 4 engine
Std 8mr or 9 head gasket is very capable
Exedy organic or std clutch is ok upto 400 if not abused

Hi, what benefits will I see roughly with the 10.5T bear in mind its the 16G one.

what makes the 4 engine hard to reach 360bhp?

Wheres best place to purchase head gasket, bolts and seals?

Sorry for lots of questions lol.

Evo turbos are all 16g
The 10.5 hotside will allow more flow of gases
The 4 engine suffers from weak ringlands and poor thrust face. It's widely accepted you can only run 1.3 bar of boost max. Some have run more tho
Search the traders and camskills for the parts your after

I'm running 1.5bar boost, at the moment and its has plenty of stick since tuned and still fine (except the valve seals and clutch lol)

Has it been mapped to 1.5 boost ??

Yea, needed a new actuator so I bought a 1.2 bar actuator before having decat fuel pump etc etc and remap. would only make 320bhp he said my air filter and exhaust restricting any more power??
