Head gasket!!!!!!!!!!!!!!!!!!?

hi, just need to know how hard it is to change a head gasket, and what makes it so expensive in a garage? is it the labour or parts???

a quick answer would be great thanks in advance!!!!!!!!!!!!!!Head gasket!!!!!!!!!!!!!!!!!!?mostly labour have to tear half the engine downHead gasket!!!!!!!!!!!!!!!!!!?Time consuming on most cars - labour is the biggyHead gasket!!!!!!!!!!!!!!!!!!?6 hours labour 180

Head skimmed and pressure tested 80

Gasket kit 80

This covers the basics only.

Varies according to the car model.Head gasket!!!!!!!!!!!!!!!!!!?What makes it hard is the intake and exhaust system. Exhaust systems are notorious for frozen nuts and broken studs. Along with this goes having to pull ignition parts on some cars.

The cost is almost all labor.

For some one to do it themselves, it will take almost (if not more) money to buy all the tools needed.

On some cars (in-line) the job can be done on two hours, while on others (V) it can take a day (or more).

If you are having this job done by a professional, they will have connections to make sure that it is just the gasket and not a warped head or cracks.Head gasket!!!!!!!!!!!!!!!!!!?Its a highly labour weighted job. You have to remove all the gear off the top part of the engine, ignition, filters, manifolds, drain the coolant etc. The head, camshaft or valves may need some work done to them before the gasket is replaced and the rebuild commenced. As well as putting it all back together the timing has to be set too, which can be a complex job. Its common practice to renew the oil and filters after this jobHead gasket!!!!!!!!!!!!!!!!!!?It's not so much the parts that makes it expensive. Its the time it takes,and you will need to have the head skimmed.Head gasket!!!!!!!!!!!!!!!!!!?To replace a cylinder head gasket you need to remove both the inlet and the exhaust manifolds, timing chain or belt covers and belt/chain. Drain the coolant, remove the rocker cover, loosen all the head bolts and then remove the head.

Once the head is off ideally to should be pressure tested to see if its cracked, it should also be checked to make sure it is still straight and true. Depending on the results you may need to have the head repaired and or machined.

All the head bolt holes need to have there threads cleaned up and then you have to re-build the engine back up.

Its a lot of labour and this makes the job expensive.

Ja.Head gasket!!!!!!!!!!!!!!!!!!?its labour that puts the price up and if the cylinder head needs engineering that also increase cost.Head gasket!!!!!!!!!!!!!!!!!!?It depends on the car an 8 valve over head valve engine can be changed quickly about 2 to 2.5 hours because you don檛 have to have the head skimmed and it is easy to remove.

other cars lets say a rover 16 valve over head cam is more time consuming as you have to skim the head replace the timing belt etc.



The gaskets can cost between 10 to 60.
