Hello

have a x reg Golf 1.8 GTI 150.( 160k miles)

..drove car the other day back from Gatwick ( been away for week & weather was very cold) and upon driving home heard a rattling noise ( tapits?) and also very noticeable loss of power..

...The oil pressure lights was also coming on..Oil levels fine with recent oil change only 4 month prior.. A friend of mine suggested replacing/cleaning the oil strainer from main engine sump as he suspected too much clogging and thus not enough oil getting through

Got a garage to do this over xmas period. strainer was replaced and engine oil topped up but now there is plumes & plumes of white smoke coming out of the exhaust. have test driven it around to see if it will burn off...It wont!

I know the car is old but it's been looked after ok and last 2 MOTs passed straight away.

Any ideas as i have horrible feeling that my engine is screwed

How noticable is the loss of power? A big drop in power or just a little drop in power? No oil lights came on in mine, but all the oil was sucked out the sump into the exhaust, hence all the white smoke!

Sounds like a possible oil seal leak in the turbo! Might be leaking gradually!? Mine went just before christmas big time. There were huge plumes of white smoke and virtually to no power at all! It was still faster than the Skoda Fabia 1.4 i used as a cortesy car though!

As above, turbo or (hopefully) a blocked breather.

I'm assuming it smokes on idle, so open the filler cap and take the breather hoses off of the crankcase and block (if you're unsure of these post a picture and we'll point them out). You can try just the filler cap in the meantime.

If it stops smoking with those pipes disconnected then you're half way there, find the blockage and get rid!

Best of luck!

Thank you to both posts above.Power feels approx halved.

It does also smoke incredibly on idle. Will try your advice next week ( left car at uncles to drive back to London) and let you know how I get on

Lets hope its the breather! If not in your opinion is it worth investing in a replacement turbo and approx what should i pay?

yours ignorantly

thats what i unfortunately think. Just to clarify from my rudimentary understanding of turbo's gven that they create higher compressions of air and so if broken would that still affect the oil pressure/reduce the oil pressure?

If the oil seals have gone on the turbo bearing, then due to the high pressures in the turbo it'll be sucking oil out from the bearing into the exhaust (hence the smoke)! Check your oil level. Mine was virtually empty after 7 miles driving it home! Low oil levels can cause the oil pressure waring light to come on. I wouldn't risk driving it personally. You don't want to kill the engine, plus you don't want to blind other drives with all that smoke! I got mine towed to the local VW specialist. If you have breakdown cover through your bank account, they should tow it for free for you!

Recon turbo's cost anywhere from £450 inc VAT upwards! Then there's the fitting, plus new oil feeder pipes, gaskets etc. if you just have the basics done by a cheap local garage, you'll be looking at about £700-£1000 all in!!

If it is the turbo...

Rather than getting a new engine straight away, have it checked out then get a 2nd hand k03s (you should currently have a k03 on your AGU) from a breakers.

Then take it to R-tech and they'll be able to map it up to a minimum of about 210 bhp!

Look at this as a sign, your car obviously wants to have lots of power and by blowing this up its only going to cost you ~ £400 + ~ £250 to make it feel like a brand new beast [:p]
