Sorry to start with bad news

Hi guys, great to be here. I visited the stand at the classic car show and was very impressed. Sorry to start on a bad point but I had a little issue yesterday. I was late for my nephews christening due to helping rebuild my friends mk4 golf engine so I was giving my '94 UK twin turbo a bit of beans to get there when it started smoking fairly heavily. By the time I got home the rear of the car was covered in a film of oil. A friend said that this was a turbo seal but I was wondering if anybody had a more definitive idea of what it could be. Cheers in advance.

It definitely sounds like the turbo seals mate. The intake side of the intercooler is often covered with oil when the seals go, it may be a good indication to set your mind at ease.

Don't bother with trying to repair them, get your membership paid for and head over to the for sale section to put up a wanted add for a set of second hand tubbys. Saves a lot of hassle. If you're into rebuilds you should be handy enough with the spanners to swap them over. Take lots of pics and lots of notes so you know how it all goes back together.

Cheers. Unfortunately my boss decided to send me to Dorset for the week so I can't get a look at the intercoolers until Friday. I'll get paid up and see what I can find. Thanks.

Welcome to the club, sorry to hear about your troubles. Any pictures of the sup? We alsk have a uk spec register on here if you pop me the reg, mileage and a little bit about the car i can pop it on there for hou

M850VEV UK spec twin turbo. 101,000 miles, silver. Totally standard bar double DIN DVD stereo.

Lots of UK specs coming out of the woodwork recently. Welcome

Was there any other sign other than billowing smoke? Any bang or something?

A couple of years ago, I had billowing smoke, and a film of oil all over the rear end of the Sup, no bang or anything, and it turned out the oil pump had pooped itself, blown the front crank seal, and dispatched the oil under the car. In turn, burning the oil on the exhaust, causing all the smoke.

Surprised to see UK turbos running stock boost having a problem at 100,000 miles, check for other oil leaks before

ripping the turbos off just incase its something else.

My UK had done nearly 140,000 miles and no problems with half of that at 1.2 bar

Hi and welcome

I was on the stand at the nec

As said check under neath for leaks first

I had auto gearbox oil spit out breather on gearbox straight onto exhaurst after a spirited drive

Thought I'd killed it lol

Fine after it cooled down

Hello and welcome! I was at the NEC, mine was the green Supra. Yes, do some diagnostic work and we shall do our best to help.

Hi Max, i too was at the NEC ( black supra ).... sorry to hear of your troubles like others have said i would check to see if a oil pipe has either blown off or split before attacking the turbo,s

Cheers

Welcome to the club Max. Hopefully you find the leak easily, if not post up pictures, video and more description and we will help you out.

Welcome to the forum! Nice looking car you got, and hopefully it will be an easy fix to get it back on the road :-)

Welcome to the club. I recognise that pic I think I was chatting to you and possibly your dad at the NEC. (I own the silver one) sorry if I have my wires crossed.

Good luck getting it fixed, does sound like turbo seals but your millage does seem low for that.

Hey everyone. Sorry for taking so long to post again but I've been stuck working away. I finally gave up trying to get some work done on it and asked my tame mechanic. He has stripped it down and thinks it is the front crank seal. I'm assuming it's worth doing the cambelt while in there. Does anyone know the best place to get the parts in the Midlands? And yes ripped_fear it was me and dad at the NEC who spoke to you.

Chris Wilson or Toyota or toyodiy, i'd get a new CP as well and aux belt, Gates do decent kits as well

I'd have thought it would be obvious where all the oils coming from rather than he thinks its the FCS

Could the front crank seal failure be influenced by a faulty crankshaft pully? If it's causing vibration (ie failing the "tippex test" where you can see it wobble) it might be a good idea to change that as well if it is an origional part.

I've also seen it suggested that low mileage can cause seals to perish due to lack of use and causes shrinkage of the seals. Anyone back this up?

Good news is it sounds like your turbos are ok?

I've got the new seal fitted. Took it for a gentle run and there still a small leak. My mechanic said that the new part didnt seem the best fit. Will it settle itself in or has it not been fitted correctly?

Did your mechanic check the crank for wear where the seal fits ? you might need a seal

off Chris Wilson that has a slightly smaller internal diameter to allow for this.

Or its not been fitted properly

I don't know if my car qualifies for low mileage but it's a 93 with 37k on the clock with original seals and I don't use a drop of oil at all.

I have low stock on my high tension oil pump seals. Whilst i cannot guarantee a fix they do help if the pump is tired, or the crank nose has a wear ridge from the original seal eroding it. I am in north Shropshire and can post out to you. £32 plus VAT. Insured P&P £3.80
