advised i need a new engine
New to this forum and have an important question for some help, i WAS a member of another forum but no help was given.
on my audi tt i have encountered a small problem i have low compression in cylinder 3 audi have advised they need to take the cylinder head off ata whopping £520 if the problem is lower ie piston they advised an engine replacement at wait for it........£4500-£5000... wwwhhheeeyyy !
Tell what i have done and if anyone can help i would greatly appreciate it..
ran my very own compression test all other cylinder 1,2 & 4 were sitting at 1000 but number 3 was sitting at 400. i have changed all plugs and coil packs but still nothing, i had been running my car on fully synthetic oil 0w30 lucas. a mechanic advised me to place oil directly ontop of piston and retry the compression again so when done for a second time the pressure raised to 600, the mechanic then concluded its from the bottom of the engine ie a piston ring, im understand this problem can be 1 of 4 things 1. piston ring 2. valve 3. cylinder head gasket 4. cracked cylinder block.
can anyione advise me any different ??
i have been quoted £1000 to replace the ring is this a good price and can this get replaced from the bottom of the engine by removing the sump or is this a strip down cylinder head off ??
super thanks in advance....
