 Re: Dutch Green Machine
Hi Harold if you can pressure wash all the dirt off the engine, it will give you a better chance of seeing where it is leaking I'm not surprised the ride was a little hard at those pressures I do hope it makes you tyres round again John

 Re: Dutch Green Machine
In response to tire and wheel size choice.
I run 13 by 6 offset +18 works well, I wanted to run a little more positive inset but could not get them. I run 175/60/13 A539s on the front and 185/60 A539 on the rear.
I have in the past run 165 /65 and they worked well I would not run 165 on any thing wider than 6 inch wide personally, it gave a very square sidewall without the stretched look.
Currently trying a different tire pressure setup I have gone to 22 front 24 rear. I was at 18 front 20 rear and really liked it, but felt it was moving around on the tires too much in some circumstances hence going to the new setting.
The difference in ride on mine for the 4psi is surprising at 4.5 bar must be like concrete.

 Re: Dutch Green Machine
@John: Pressurewash between engine and back and rear-cab-panel would be very narrow, if you can get there at all. Maybe clean and dry the engine as good as I can, and then wrap it in rags and see where it gets wet? @Neil: Thanks for the information! Yes the ride was quite hard, but very comfortable a GTM Coupe will never be Cheers Harold

When I had the libra My tyre shop did not believe the pressures I wanted, felt very odd until I got home and let about 10 psi out.
Odd thing was Libra had same size tyres as the oil burning skoda

 Re: Dutch Green Machine
Cleaned up the bottom end of the engine yesterday and left it idling for half an hour, no oildrips found during or after. Maybe the oilleakage has been fixed after all or only occurs when driving. Or maybe the oil was not hot enough yet.

 Re: Dutch Green Machine
An old trick from years ago that i seem to remember, was to sprinkle talcum powder around the engine where you think the oil might be coming from. Then go for a drive & check it. Any fresh oil leakage is more clearly visable on the powder. May be worth a try NB. This tip is from the 70's, so Old spice or Brut probably works best

 Re: Dutch Green Machine
Two weeks ago there still was no oil under the car, I took it for a small spin of aprox. 20 minutes, placed it back in my garage, an hour later, no drips, a day later, no drips.... I was getting happy, maybe the oilleakage was cured after all.... But when I took a look under it this morning, I was not happy at all.... A small puddle of oil under the left Side of the engine and a small drop still hanging under it... Why not after I drove it and why when it was standing still...? Seems to come from the enginesupport area.

The children from next door sneak in with an oil can when you are not looking John

 Re: Dutch Green Machine
Both my neighbours are 65+, I don't think they have small children hidden somewhere... Think I will take the enginesupport off today and see if I can find the exact location of leakage. Not exactly my original plan for today, laying under it instead of driving it. Harold

 Re: Dutch Green Machine
As I passed 65 my childish sense of humour came to the fore, don't write off John's idea

 Re: Dutch Green Machine
I almost went to my neighbours with a baseballbat in my hands... Instead of that I took off enginesupport and the crankshaftpulley again. The leakage seems to come from the timingcover-oilseal, which is brandnew is is placed by myself a few weeks ago together with the timingcovergasket... Could a new timingcover help or should I search for the repeated oilseal-leakage-cause somewhere else? The crankshaft or pulley doesn't feel rough or damaged. Last time when I renewed the seal I cleaned the cover, put in the new seal, put the cover on, positioned it loosely with a few bolts, than put on the pulley to position it well, tightened the bolts, took of the pulley again, put in and tightened the rest of the bolts (Some of them almost unreachable) end than put on the pulley again. Is there a better way? I'm not very happy...

 Re: Dutch Green Machine
My geriatric childish humor is still developing, if you lived next door to me I could sneak around with a drop of oil just to wind you up  The way you assembled sounds good to me, is there any sign of wear on the pulley where the seal seats? I have always used a silicon sealer (Hylomar) on the gasket face and the outside of the seal, unless the timing cover was bent and if it was I would straighten I cant think of any reason to replace it, when it is off sit it on a flat surface to check it and also put a steel rule across the cover back plate in case that is bent.

 Re: Dutch Green Machine
If its just a few drips just park it over a drip tray - just like all kind of classic car/bike owners have been doing for years. It is a fact of life that old cars leak fluids - just like old people

 Re: Dutch Green Machine
@senzomat: Just like old people, I like my car better when not leaking in my garage. I think it's too much to leave it like it is. @John: you don't want to play with your life There are some color variations on the pulley's axl, but I don't feel anything when going over it with my nail. I don't have the cover off yet, just wondering what to do next, get a new seal? Get a new gasket? Get a new cover? Get a new pulley? Get me silicon sealer? Maybe putting silicon sealer between cover and seal would be enough, but I don't like the idea of taking the cover off again when it still leaks after placing the sealer..... Harold

 Re: Dutch Green Machine
Easy option as Sanzo said get a drip tray  but in spite of my age I DO NOT need a drip tray next option get new seal, gasket and sealer check the cover on a flat surface and put a steel rule across the back plate to check its flatness. John
