BogMonster Posted February 19, 2008 Share Posted February 19, 2008 Welcome. This site approves of the use of punctuation so there is no need to be afraid of , . ? ! ; and : It could be the head gasket now, if it has been boiled a couple of times, but for the original leak you might also want to check out the radiator where the end tanks are crimped onto the radiator matrix, it is not uncommon for them to leak there - signs of lots of pink coolant stains are the giveaway. Also check the header tank cap is actually holding pressure as this can cause the water to boil. Quote Link to comment Share on other sites More sharing options...
lynall Posted February 19, 2008 Share Posted February 19, 2008 If hoses pressurized almost cetianly head gasket. As said once head gasket done your rad will then leak as the excess coolant pressure will have knackered the end tanks about £120 ish e-bay Lynall Quote Link to comment Share on other sites More sharing options...
gazz1969 Posted February 19, 2008 Author Share Posted February 19, 2008 sorry about the punctuation!!! i am a one finger typer, right have removed the head today looks like number 3 and 4 are leaking into the waterjacket. head is going to be pressure tested tommorrow for cracks then the task of reasembling oh what fun. i think rad and header tank and cap is holding pressure but i think i will change the thermostat aswell Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted February 20, 2008 Share Posted February 20, 2008 And fit new head bolts as well Quote Link to comment Share on other sites More sharing options...
BogMonster Posted February 20, 2008 Share Posted February 20, 2008 Have a very close look at the bores as the last one I saw a head off had a six inch crack top to bottom in No. 1 cylinder, which explained where the coolant was going Quote Link to comment Share on other sites More sharing options...
cipx2 Posted February 20, 2008 Share Posted February 20, 2008 ... and your engine might need new plastic/steel head dowels, depending on when it was manufactured. Quote Link to comment Share on other sites More sharing options...
gazz1969 Posted February 20, 2008 Author Share Posted February 20, 2008 head has no cracks!! plastic locating dowels were in a bad way, bores are like new ,got to regrind valves as they are a bit pitted . but other than that spoke to a specialist today about skimming and he said it is ok to skim but maximum of 10 thou only no more will be organizing new parts gaskets soon ps are there any issues with the timing chains as there are new kits for about £100 just wondered if there is an issue with any off it????????

JimAttrill Posted February 21, 2008 Share Posted February 21, 2008 No problems with timing chains that I know of, you should save your money. Quote Link to comment Share on other sites More sharing options...
gazz1969 Posted March 8, 2008 Author Share Posted March 8, 2008 hi all, right all finished parts needed were as follows headset including headgasket was about £60.00 head bolts £38.00two steel dowels £1.50 skim and pressure test was £86.00 i also replaced the thermostat £12.50 and timing chain tensioner as the nylon wear strip was broken £24.99 i would say the job was not to bad to do you can buy the timing pins for about £4.00 (found after i had done the job ) setting the injectors was easy they must go back in the same place they came from but overall the job was not as bad as i was led to believe by a local diesel specialist who then offered to do the job for me!! many thanks to all off you and sorry for the punctuation i am better with my spanners than this thing!!!

Stryger Posted July 12, 2021 Share Posted July 12, 2021 replaced head gasket but still looking pressure. Pipes are all good. Head was skimmed. However did not paint the gasket with aluminium paint before insulation. Quote Link to comment Share on other sites More sharing options...
