seised engine!

[frank galager]

Hello there fitting a new engine in my golf 8v. Its been sat for a while an seems to be siezed which im not to worryed about, should i be?

Also need to change all the belts, surely if its seized i won't need to worry about timing an stuff just a case of changing them over right??

Is there any other tips anyone can think of for an engine change? never done one before so any help would be great!

By seized do you mean it won't turn over? Have you checked starter motor is actually functioning correctly?

How long has it been sat? Did it turn over when you first cranked it then seized?

Depending how long it's been sat I would have changed the oil and oil filter and given the plugs a good clean.

Is it your old engine that has seized or the replacment

The replacement seems siesed, it's not it the car yet so can't turn it over. Guess thinking about it it could not be siesed, just assuming it is. It been sat In a garage for over a month.

Well if it has been sat around and will not turn over then it is not a lot of good.

Try a bigger bar on the crank pulley and see if it will turn over.

If it has been stored in the garage and was OK before, I doubt it is actually seized. Unless the cambelt has snapped and a piston is up against a valve - check that first and find TDC on the cam if so.

The most common way to seize a stored engine is to leave it out in the elements with no spark plugs in. Water gets in, the piston rings then rust to the bores, seizing the engine.

If this has happened it can be freed if you are lucky. I have done it with a fitted engine by rocking the car in top gear. If you are unlucky your new engine is scrap.

Don't try the belts without doing the timing. It is very unlikely the cam is also seized and that will rotate once the old belt is off.

Since you are currently looking at a scrap engine (and assuming the cambelt works) I would get a bit savage with a long bar like Wayne said. If you can free it up you have a spare engine. If not you get a few quid for weighing it in.

Ok then it probably isn't seised, its been in side an the plugs are still in. Whats TDC?

Ok so got to sort the timing out then. Got ya

The old engine is fine, its the gear box thats knackered, got a gear box an engine complete for a good price, an the new engine has done about 50k less than mine so just gonna swap it all over. So will have a spare engine.

Thanks guys.

Why not just swap t gearbox and keep the engine incase you need it in the future?
How many miles has the current engine done? Has it been serviced regular?

Yea if their is nothing wrong with the current engine why risk another? Mileage usually plays no part in how healthy it is

My engines done 170k the new ones done 90k it's been well serviced.

I'm changing the engine 1 because I thought while I've got one with lower miles and I'm already changing the gear box I may as well. 2 because I thought it would be good fun an experience! The new engine seems in alot better nick than mine, which before I had it 3 years ago had been very poorly looked after.

I see what your saying though but I've already started now so I'm gonna finish if it doesn't work I can just swap em back, which would suck but hopefully it won't come to that.
