Hey,

I got a RB20DET in a silvia.

Just drove my car seems to be alot of steam or clear smoke not white coming from what seems to be around the rocker covers.....what could this be does not show on the temp dial thats its overheating.

But is has caused the car to stall twice so far and it wont kick over until you leave it for 5 mins.

I need any help i can get ASAP.

- Thanks Luke

I'd stop turning the engine over incase you're doing any more damage.

Does it smell like oil?

Do you have oil in your radiator? Do you have a full radiator?

I'd be looking for oil or a exhaust leak - depending on what it smells like.

Head gasket let go perhaps? did it occur after spirited driving?

The temp guage will read normal if there is no water in the system....it needs water to function correctly.

If you drove it till it stalled and did that a couple of times you will have warped the head. If may drive ok once the leak is fixed but get a leak down test done and find out how bad it really is. Another problem is that the turbo would have overheated severely also so there is a good chance that once you fix the problem, be it water pipe, welsh plug or head gasket, the turbo may have damage to the bearing which can cause them to fail soon afterwards.

Another problem that you will have to check is piston shrinkage. If it turns out to be a head gasket blown and you drove it until it stalled there is a good chance your piston can shrink in size once cool again. Make sure you get this checked out by whoever does the head work - BTW it will cost at least $600 to repair the head if it is warped.

have you found the exact point the fluid is coming out?

i had some trouble with my r33 dropping coolant but only after giving it heaps, never lost any thru normal driving. it was dripping down off the bottom of the block. traced the leak back to a tiny pin sized hole in a coolant line close to the block, guess that the leak was forced due to higher temps/extra pressure in the lines.

have since covered and clamped the hole (no more leaks even after hard driving), and am replacing the lines this weekend.

not sure if this is relative, but may be worth checking.

maybe a cracked block?

Look, engines run on smoke.  Once all the smoke gets out they are dead.

aaaahhh, i see you are wise in da ways of da smoke. applies equally to electrical systems particualry those installed in pommy cars and affiliated with lucas aka the prince of darkness.

You will be looking at a minimum of around $1000 to do a head gasket on one of these if you go through a workshop.

$1600-$1800 if the head is bent (which it more than likely is)

$4000 if the pistons have shrunk.

Good luck, let me know if you have any issues. I have dealt with many of these.

    • To back this up, I'm always looking on the outside, seeing the level, and then opening it up anyway, as I'm worried the level I've looked at, is more so a scunge line. Then you end up dipping your damn finger in it too depending on the type of tank you're looking at just to make sure I'm not going insane.   PS, Mark, polish up the none moroso one a bit and then give it a clear coat. The Moroso one looks to be way shiner (not mirror polished, just shinier) and it'll still look weird with the two different alloys beside each other. Either that, or Id probably paint them a flat black...
    • Good old Orange Park hey... 😛   f**k I miss that race track
    • lo, it was a death trap. Good times. Got any Fatz Drift Day DVDs still available?
    • Yes, overthinking. Many PS reserviors are completely opaque. Our Skyline ones, for example. Have to remove lid, peak inside, swirl the dipstick, try to remember how to read it, etc etc. Normal. Radiator overflows are often sufficiently opaque and scunged up that you can't see the true level inside anyway, and have to open and have a peak. Besides which, I replaced the (massively expensive, even back then) plastic overflow in my Alfa GTV, back in the '90s with a stainless one that I had a good fabricator make up to be dimensionally same-same, that looks remarkably similar to the Bogan's Moroso one above, and I never suffered any particular paranoia that I didn't know how much coolant was in it.
    • Looks great, but I'm always concerned that it makes it difficult to see what level the fluids are at. Am I overthinking this?
