samurai head gasket ?

(1/3) > >>

ben.williamson:
hi i have just bought a samurai off ebay 1300
basicly there is a substance in the oil filler cap
but not allways

symptoms include when i picked it up the water level was higher than the maximum in the coolant res evior

now after the week end (picked it up sat drove it home 150 miles and went to kirton lindsey on sunday aprox 100 mile round trip + offroading for 5 hours + a bit of driving round etc 3 miles maybe) the water level has dropped to just below to full mark

bering in mind the sj is lifted 2'' and has 31 tyres it went evry were up the steepest hills etc so maybe some coolant has been lost due to this overflowing maybe

cheers ben

ps i have lookd at lots of forums and can't find anything

also if the head gasket is gone how difficult is it do ? whats involved cheers ben  :)

Hi Ben

If its overfilled its quite possible it's blown it out the expansion tank.

If the substance is like a greyish goo its possibly water in the oil, and thus, head gasket. Best thing would be to clear it out so the cap is claen, take it for a spin and see if you get more. Condensation can form in the rocker cover, it shouldnt, but it can.

If its like a Vit, then both manifolds off, fuel pump, timing covers and belt (mark them before you take it apart!) then off with the head. New Gasket looks to be about £17 ish and a set with all the associated gaskets comes in at about £50 (head, rocker, fuel pump, intake, exhaust, possibly carb).

If you replace the exhaust and it has the nasty heat sheilds make sure you put a tiny hole in the sheilds else the plug recesses fill up with water.

Have done it on a vit in a day :)

when itst there its like say moyo or salad cream but its only there when youve been driving for 10mins turn engine off wait two or three then look if you look when cold nothing or when hot nothing

cheers ben

Get yourself a compression tester and take a look. Disconnect the LT wire from the coil and crank it over checking each cylinder in turn. A problem in a cylinder will be indicated by a bad reading. If you have the haynes book of lie it does say how to interpret the results. Low compression can be caused by a few things but its a good indicator that the head needs to come off.

It does sound like you are getting water in the oil which is a head gasket or possibly other damage to the head/waterways.

ben.williamson:
seams to run perfect

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
