Blown Head Gasket.

[InTrenches]

So today my car got really hot when i lifted the bonnet my radiator was almost dry.

so i got on my hands and knees to looks for a cracked hose or loose connection etc untill i finnaly checked my oil.

which to my dissapointment was milky.

 

so, when i get a new head gasket, i have the next task of checking to see i havent cracked my head :bash:

 

I'm hoping since i don't drive like a retard and look after my engine that my head isnt cracked.

 

however if it is I'm thinking of getting a 4k-e head and manifold, to make my next purchase of a turbo easier to install.

 

good or bad move?..........thoughts?

 

also i plan on getting either two copper head gaskets or preferably a metal.

 

anyone know a good place to look?

 

 

Cheers Isaac

A 4ke has dished piston, hence there is less compression chamber in the head. If you put a 4ke head on a 4kc then you'd actually increase the CR which is not what you want for a forced induction motor. If you put the 4kc head however on the 4ke theis would give you a boost friendly motor.

I used to boost an internally stock 4k to 15psi and never had no real issues so if you want to stay with the 4k (instead of say going for a 5k) then leave it as it is.

 

As for the head gasket, you can't really run a copper gasket unless you o-ring the block/head. And running 2x of any gasket is a really bad idea. There isn't a Cometic or anything you can get for a K series (trust me I enquired about it) but honestly I think the best gasket you can run is a genuine toyota one. Combine that with some ARP head studs and you should be fine. This is what I'm running (gen toyota gasket and ARP's) and I've boosted this motor to over 20psi.

first of all wow 20psi is huge, secod i have a 5k block with 5k head can you tell me the repercussions of running a 4K-E on the 5K then boosting?

 

is it an option to keep the 5k head and just use the EFI manifold off a 4K-E?

[Taz_Rx]

5k and 4ke are both dished piston motors, hence using a 4ke head on the 5k (or vice versa) will give you basically stock CR.

 

Using a flat top piston head on a dished piston motor however will give you compression chambers in both the head and piston, and hence will lower the CR. A 3k head on a 5k will be around 8-8.5:1 and using a 4k head on a 5k will drop it to around 7.8'ish-8:1

Running either the 3k or 4k head on the 5k will also require changing to solid lifters.

thanks very helpful info. any knowledge of anyone getting rid of an EFI manifold? or the best place to look? ebay? u pull it?

 

also should i be going to u pull it for the lifters? or ask about on here?

 

any idea on the cost of solid lifters?

[InTrenches]

ohh wait up i just found a very usefull blog, its probably been posted on here before, so many helpfull photots etc

Yeah I've got chev lifter and A12 (Tomei chrome moly :bash: ) pushrods.

 

Try some commercial wreckers (vans and trucks) and ask if they have any KR42R twonaces to try and get a 7ke manifold. 4ke setups are way overpriced and frankly shit.

u pull it do the trick for the manifold?

 

and whered you find the tomei pushrods? do you have any oil pressure problems running the chev lifters?

 

i heard if you don't convert the 5k hydro ones you can loose pressure.

If they have any KR townaces.

 

Another member here bought the Tomei's (they're just aftermarket A12 ones) and didn't end up building the project they were for so he sold them to me. Sorry don't know where he got them from.

 

No oil pressure probs at all. I run between 60-80psi while going for it and it'll drop to 20psi at idle.

[InTrenches]

how much you buy the tomei's for? cause a site in america wants $12 each american then i have to pay postage. sound like a deal or shit?

 

 

also do you know what chev engine your lifters are from? I'm gonna ring u pullit and give them a list of shit.

I got them for $90 posted.

 

I think they're small block chev ones, but I'm really not 100%. I bought them from a RC member who sourced them somewhere.

 

...sorry I know I'm not being overly helpful here.

Thanks, if you don't know you don't know, don't stress.

 

cheers for all your help.

 

ive got the rocker cover and waterpump etc off now, water pump is shagged, the outlet is all broken up and erroded (spelling?)

 

so I'm gonna buy a new one monday, hopefully have her back up and running soon.
