want to do a test on mates car what and where can we get the sniffer tester seen used?

 

dan.:)

ebay sell them. Just make sure you drain some of the rad water when you use it ;)

sealy do this sniffer,local tool store or motorfactor will prob supply.

thanks for replies looked on ebay but couldnt find it what does it come under? failing that will try halfrauds.

Go to mills in Redruth dan

sorted thanks to a ward's mechanic! sniffer shows head gasket gone looking for a "how to" link if anyone can point me in right direction! :confused:

I dont think there is a complete headgasket "how to" Dan.

 

Its a engine out job (there are guides for that)

then plenum off (guides out there for that, and I think you've done that)

lower plenum off with fuel rail

then Remove each head

Replace headgaskets

 

Really you should get the heads sent off to an engineers to be tested too.

^^^^^^^^^ Yes not worth all that effort and not having them skimmed.If the heads are not warped now they probaly will when you undo the bolts.

thanks legrath /jimmer so it cant be done with the engine still in? has to come out.

 

dan.:)

it can be done in situ if its a turbo model but it would be far easier to remove the engine.

i tried to do the heads with it still in car dan, after nearly a weekend gave up, and took the engine out

Its a common misconception nowadays that if a head gasket fails the head should be skimmed,this is not so.In doing this (if its unnessary..) only thins the casting and in the event of a future serious overheating will likely result in the head cracking and be scrap,whereas if un skimmd would likely warp and be repairable with a light skim..

It usually needs a serious overheating to warp ie,driving the car for a period with it boiled.

Theres also issues on a turbo motor running a higher compression ratio if you dont fit a thicker gasket.(although raised comp is good on a n/a motor)

 

Check the head with a true straight edge,a proper engineers s/steel rule (theres straight and theres straight)or similar,and for about 25-30pounds for peace of mind get it pressure checked for any cracks if u like.

In the past 15-20 years doing customers headgaskets id say 30% actually needed skimming,that was a change from cast heads which cracked so easilly to todays alloy heads.

THANKS FOR ALL YOUR ADVISE! me and west been at it for 6 hours and with a phone call to paul@swz for help:bow: we nearly got one side off!:confused: will be asking some questions so hope you all willing with helpful advise! and before anyone says it west aint going to scrap it!:tongue:

Your doing it with engine in Dan ?

yeah giving it a go! :eek:

 

dan.:smash:

we got both heads off :headvswal so now looks like the bottom end out and a new engine in! any tips?

How come ?

A common misconception yet regarded as the correct and proper way?? id rather have to explain the cost to many of my engine rebuild customers then apologise that i did it on the cheap and it went wrong.alloy heads can be a pain to clean up after removal so a light skim gives a good surface for the new gasket especially if steel multi layered ones are used which are far less forgiving than asbestos types.I really dont see how around 6 thou removed from a face is going to weaken it that much or cause compression issues unless your running very high boost pressure :rolleyes:.

cant seem to find any visible probs with head gaskets, so having heads tested. WHY SO MANY BITS!:headvswal

 

dan.:smash:

Sometimes when cars are overheated the heads lift with the expansion and the gaskets stop sealing.Did the bolts feel a little looser than you expected?

no some were tighter than others near the back.

 

dan.:confused:

bin busy cleaning up getting ready to put back together!

NEARLY THERE! :dance: all rebuilt just waiting on some odds and ends before it goes back in.:hyper:

 

dan.:D

we just finished putting the engine back in and all attached i need a set of smaller hands though!:) very pleased though hopefully have it started by end of weekend time allowing.
