Probably, I'd be more worried about what further damage has been caused by blocking the breathers. White smoke is usually coolant (head gasket etc), blue is usually oil (piston rings etc) and black is usually caused from running the engine rich (not necessarily a bad thing).

you really should know what mods are done to it before you buy it...

if your unsure of what blowing smoke could mean then you pretty much need some help and eventually I reckon this thread will say 'take it to a decent workshop'...

i can tell you why is it blowing smoke but just wanted to see if anyone els would say it

so looks like the turbo has gone and the blocked of rocker cover breather would of been just adding to it ( now that it was blocked off i just hope the seals have not been push out)

i know this is kind of off topic but not really

but i'll ask anyway

my car will sometimes blow a puff of white smoke when i'm in traffic and take off sometimes and maybe drop the clutch a bit early like it bogs down a tiny bit and blows a bit of smoke

is that normal?

fine on acceleration and normal driving though

Hey was just wondering about my car, ever since its been tuned its been blowing alot of black smoke. Like i mean i wash the car and within 3 days the whole back of the car is black. Which looks really bad considering the car is white. Anyway what im trying to get at is do you think its possible the tuner has made it a bit over rich? and could get away with it running a bit leaner? or the tune has slightly gone out of wack since it was done(9 months ago) and needs to be redone?

The pressure built up would cause oil to be forced down the valve stem seals...also more likely the pressure in the sump would restrict the turbo oil return and pressurise the turbo housing forcing oil out the turbine oil ring. I wouldn't expect it wouldn't damage anything in the short term however if it has been doing it for a while the caked and burnt oil could have worn the turbine oil ring.

      Surely the merged entity will be called "Honda" given the relative company values. I've got to be honest, I don't understand how merging 2 companies that missed EVs (despite Nissan making the first mass produced one) will solve their problems

      How "plug and play" is the Haltech Pro for R33 GTST

      By Murray_Calavera · Posted

      If you haven't bought the ECU yet, I would strongly consider buying a modern ECU. Yes it is very easy to setup and tune, however it is lacking many of the features of a modern ECU. The pro plug in is something like 10 or 12 years old now? Can't remember exactly but it is very dated now. In that time the Elite was released and now we have the Nexus platform.  I would strongly consider not buying the ECU that is 3 generations old now (especially as it isn't a cheap ECU!).

      Steps to DIY sanding car back ready for respray....

      By Murray_Calavera · Posted

      Sorry I should have been more clear with the previous post.  The block is a sanding block - picture something like this https://motorguard.com/product/motor-guard-bgr161-bgr16-1-rigid-psa-sanding-block-2-5-8-x-16/ The guide coat is the paint It's two separate things I was talking about, there is no "block guide coat".

      Maybe more accurately, you aren't just dulling the existing paint, you are giving the new paint something to 'grab on to'. By sanding the existing paint, you're creating a bunch of pores for the new paint to hook on to.  You can lay new paint over existing paint without sanding it, might last a year or two then sad times. The paint will peal/flake off in huge chunks. By sanding it, the new paint is able to hang onto it and won't flake off.  Depends on the primer you are using. When you buy your paint, as the paint supplier what grit of sand paper to use before you lay down the primer.  Use whatever you like as a guide coat. Pick a colour that really stands out in contrast to the paint. So say your sanding/painting a currently white car, using a black guide coat would work well. You very lightly lay the black guide coat down, then as you sand the car with the large block, all the high spots and low spots will stand out as the black paint is sanded off (or isn't sanded off).  When you buy your paint, hit up your supplier for recommendations for what paint to use for a guide coat if you're unsure what would work well with your setup.
