Hey all I went to my first drag meet in casino on the weekend, It was a good turn out over 120 cars n they havin another meet on the 23rd of may for more info go to www.summerlanddrags.com

Anyways my best time was 8.36sec on the 1/8th mile it was pretty hard to get traction as it was a street surface (airport strip lol)

I done 7 runs on the day and after the second last run the car sounded a little different.... i thought nothing of it really and done a last run and it didnt have near the same power as the last run and as i looked behind there was lots of blue smoke... as i limped the car back to the pits it definately sounded like its kinda missing in one cylinder, as if its lost compression. I poped the bonnet and saw oil around the blow off valve and oil sprayed on parts around it, now im thinking the engine has bad blow-by in one or more cylinders and i dont have an oil catch can. basically oil is getting pushed into the intake i believe causing the smoke... the car made the 80km trip home fine but still dont sound right.

So basically i believe i need a new engine soon and as I live in yamba nsw on the north coast where would I be able to buy one?

I wanted to swap my turbo gtr injectors n the like onto the fresh motor

im fairly mechanicly minded so i can do most things myself but cant build an engine lol

Any help would be appreciated, Cheers

I found the exact same problem on my car yesterday mate.

I'm getting a catch can and then driving round for a week or so see if its excessive blow by or dead rings. Or the turbo.

Maybe try the catch can, or do a compression/leak down test before you spend $$$ on a new engine.

yeah do what floydwestwood has said as i replied to his post yesterday,

but definitely sounds like you need a new motor or rebuild your current one.

hit up jap wreckers for pricing on a new RB20, justjap, SSS to name a few.

I pulled the intake piping off to find a pool of oil lying in the bottom of it today.... :down: I mean a fair bit of oil too so i took off the intake to the turbo off to make sure its not my turbo oil seal thats goneski and there was a pool of oil in there too so basically i need a catch can now.

I also checked all the spark plugs to see if any were fouling (making my car sound its lost 1/2 a cylinder) only the plug in cylinder 3 was oily and i mean the thread and the outer electrode but the tip wasnt oily! this must be the bung cylinder i guess, im going to clean the oil out of everything and buy a catch can for the car and see how i go,

if it dosnt get better and i dont get my cylinder back i guess its new engine time :P

      Possible swap on R34 RB20DE NEO?

      By Kapr · Posted

      Hi. A little bit of an update. It maybe(hope not) looks like i would need a new tranny(it would be "maybe" a cheaper or better option anyway) So i need some info. I know i need a different propshaft(i can make custom one) LSD is not a problem cuz the engine will be still(for now) N/A RB20. So if i buy RB25DET NEO tranny...is there something else i need? I read something about push/pull type but i do not know if i need to "change" something or i can just plug n play onto my engine a go? Thanks for the advice

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      Mistakes were made, my R34 Story

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..

      Lower A arm Skyline v35

      The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.

      Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????
