After some advice here please?

 

Towed home last night by AA - looks like head gasket has gone. Does anyone know anyone near Liverpool who can do this job and any ideas how much it will cost me?

 

Or, might have a go at doing it myself - best place for getting gasket set from please?

 

thanks all

Heavy right foot Trev? Hope you get it fixed soon mate.

Gasket set from Mike Feeney or Luke at ZCentre

James Corcoran on Facebook has a garage in liverpool. He might just do bodywork though but worth asking.

Be aware Trev, the term head gasket failure is often an incorrect description, head gaskets, especially on the 300zx do not fail on their own, there is always a cause. Just changing the gaskets will not effect a repair on its own.

 

So the failure of the gaskets ability to seal in the water between the head and block is usually the result of one or both heads warping, ( alloy heads on a cast block ) this could of been due to water loss, failed water pump or pin holes in the head surface.

 

So a full water system check is required to see where the original issue started out, and then the heads will need removing ( can be done in the car easier on non turbo ) and sent away for checking and skimming if the rest of the engine is ok.

 

The block will need a through check and the tops of the pistons and the cylinder`s condition checked and even measured for wear, of course this strip will require you do a cambelt change, even if the existing belt looks ok. New belt pulley rollers, new water pump, new tensioner and by pass hoses, then on to ancillary belts.

 

The cost of this job in parts os not insignificant, do not be tempted to just change the gaskets, not skim the heads and fit the old belt on, this will be a recipe for disaster.

 

Good look and and use the search button on hear, plenty of info.

This is the level of stripping required, this however is a non turbo engine which is significantly easier in the car, but turbo can also be done.

Get a test done like this first >>

 

 

 

 

thanks for the advice jeff.wishing you where still here to fix it again. had all this done in 2014.finding a good mechcanic seems to be an ongoing problem these days.i can skim the heads in work but may need to get leak tested somewhere else.think i'm going to need some good luck.

hi jeff.

think the head gasket has failed due to overheating.i was exiting the motorway when i heard a gurgling behind the dash.had this before

and i was loosing water at the heater matrix.saved it that time.not so lucky this time.i pulled over and seen white exhaust smoke.only then did the temp gauge go up.

you did a water bypass for me when you replaced the heads in 2014.so ill have to check all other possible places for leaks before a rebuild.the radiator water smells of exhaust fumes so think that is what has happened.

many thanks again for your advice.

Ah damn that sounds like an over heat from lack of water, the temp guage is a mare for this, I have said many times a water level indicator warning light would be so much better, and likely easy to set up, remind me is yours turbo or na?

 

Jeff

its a na jeff.last time it bent valves and you had to fit two heads.at least hopefully it will only need a rebuild this time.

not a bad idea fitting a warning light on the water temp.could save a lot engines.

I have an NA engine available if you want to do a swap ?

hi jimmer.

thanks for the offer but i think ill probably go down the rebuild route.if there is any major damage to my engine i will have to think about putting another engine in,

hopefully not but i'll have to wait and see.

thanks again

i do both body and mechanical work, currently limited to what i can do where i am but thats going to change soon, think trev has had a few parts off me and came to see me about sorting a few bits on his car yesterday
