what would be involved with doing head gasket

what would the effect be of just using it offroad do you think i don't use it every day

Before any of this do a compression test and verify that anything is wrong in the cylinders. It will eventually start to die and act up and you can make things worse running on a blown gasket. Depends on what abuse it gets but it will die.

Firstly. Get a book of lies, the hardest and most potentially damaging bit is the timing belt, get that wrong and your engine is potentially toast. If you arent happy about that dont try. on the other hand, mark the belt, pully and the dizzy reletive to the head and you'll be OK. Use a good set of tools and you'll need a torque wrench and the booke of lies again for torques, or ask us niceley. Keep everything clean and label wires and hoses and please please remeber to disconnect the battery. Take your time and recheck everything and you'll be fine.

From memory on a Vitara CFi and going on looking at my own carb one that I have to do this weekend it should be something along the lines of removing the filter, carb and intake manifold. Mark the plug leads and pull them away, mrk the dizzy mount on the mount and the cylinder head so it goes back in exactly the same place then have that off. Then undo the downpipe and take off the exhaust manifold. Remove the fuel feeds to the fuel pump and clamp them off, remove the fuel pump and gasket. Take the timing ocver off and remove the belt, slacken the tensioner and it should slide off. Not having the rad there will make this easier and you need to drain the coolant anyway. Remove any remaining hoses and wiring, LABEL THEM and then off with the rocker cover if it isnt already. Undo the eight bolts in the correct order (again haynes manual or someone here can give you that) and then tap it till it liftfs off and off you go. Ideally you should have the head skimmed and check the blocks surfaces are good etc.

You'll see a blown gasket quite quickly, be careful with the head/block mating surfaces. Then it all goes back together the same way it came apart. Make sure everything is torqued, right things to the right place etc. Ideally the head bolts should go into the same holes they came from or be new.

While its all apart consider cleaning it up if it needs it, decarbonising the vlaves, pistons and head, look for damage to the valves, pistons and head, things like excess amounts of soot and carbon may mean you are running rich, oil in the bores in any quantity is bad too. Check the valves are round and centered. I've seen two vits eat the exhaust valves.

Its potentially a huge job and I wouldnt suggest it as a first time job, butthe haynes manual seems to be ok on the procedure and if you take your time, keep things clean and use the right tools it shouldnt be a problem. Do an oil change right after and the bit about taking it for a spin then re-torquing the heads is important. Also on one we took the opertunity to get the head refurbished and flowed before refitting it.

Both of my rebuilds are comming up on 40K since the work was done and fingers crossed, no issues.

I cant stress enough the clean bit though, jetwash the engine bay first and be careful. A speck of grit can wreak havoc with the bores and potentially write the engine off.

ben.williamson:
realistly is there any thing i could do to check this first, some one once said ''lime water'' i don't know, to check head

as the local garage i use are asking £30 to pressure test it  

the car runs as sweet as a nut and dosent get hot either temp gauge (or heater inside car) it always sits about 1/3 on temp gauge

i have done a lot of my own macanics but its hard work and i can't really be bothered how much do you recon a job like this would cost

compared to an engine swap / 1600 16v vitara engine or any better sugestions

cheers ben

Steady on a bit....

Some vehicles get milky deposits as a matter of course, I don't think the Zuke is one of them, but how ong has the ar stood for before you bought it?

I would change the oil and filter, flush it through before draining with an engine flush and see if it still does it....

You can also ask a garage to test for carbon on the water, you put some funny blue liquid in a tube and hold it in the water tank if there is carbon it turns green / yellow if it stays blue the gasket is fine....

smart cars oils caps go milky when the breather is blocked.... merc Vito's too.... I'd test for carbon first!

rhino-force:
Hi there

The goo on the filler cap is not unusual and i would'nt worry to much. Just keep an eye on the temp gauge and water levels mainly in the rad its self. Pretty sure its fine.
