Les Henson Posted June 26, 2016 Share Posted June 26, 2016 Not if it's a K-series. Wet liner engine. Les. Quote Link to comment Share on other sites More sharing options...
johnnycash1 Posted June 26, 2016 Author Share Posted June 26, 2016 yep 1.8 k petrol, ok it is a git to get the crank timing right after. i'm doing the cams so valves will be fine, only think is the oil ladder, will have to take sump off to make sure everything bolts back up. dave Quote Link to comment Share on other sites More sharing options...
Les Henson Posted June 26, 2016 Share Posted June 26, 2016 Crank has to be set before the head is fitted as this puts all the pistons halfway down the bores. The cams can then be set once the head is refitted and then the timing belt. Quote Link to comment Share on other sites More sharing options...
johnnycash1 Posted June 26, 2016 Author Share Posted June 26, 2016 Hi Les do you think i'll have to take sump off, does say oil ladder should be held in with 2 of its own bolts, so should not have moved? i think it should be ok? your new friend dave Quote Link to comment Share on other sites More sharing options...
Tim2809 Posted June 26, 2016 Share Posted June 26, 2016 Liners wont have dropped. 2 would have lifted when you turned crank. There are seals between liner and block to stop oil getting into sump. You will probably have to remove all 4 liners and change seals Quote Link to comment Share on other sites More sharing options...
Les Henson Posted June 26, 2016 Share Posted June 26, 2016 I've done dozens of head gaskets on this particular engine. If the liners have only lifted a small amount, then press them back down. I've never yet had to remove the sump and if the head bolts will screw in, then there's no problem.

johnnycash1 Posted July 3, 2016 Author Share Posted July 3, 2016 ok update. back together, running sweet, but but but, after a while water level is rising to top of exp tank? she is not getting hot. temp gauge smack in middle. coolant fans never come on. been trying to bleed coolant system. no water in oil? any thoughts dave Quote Link to comment Share on other sites More sharing options...
Les Henson Posted July 3, 2016 Share Posted July 3, 2016 You have to bleed the cooling system. Did you do that? Les Quote Link to comment Share on other sites More sharing options...
johnnycash1 Posted July 3, 2016 Author Share Posted July 3, 2016 8m bolt water comes out, then screw on heater hose. just thinking if it was the gasket or head still would it not be bubbling? why water level rising out of tank? dave the head must have gone, coolant keeps over flowing???????????? les where you live?

Les Henson Posted July 4, 2016 Share Posted July 4, 2016 Water rising without bubbles is usually an air lock. As the air is heated it expands and pushes the water level up (when you switch the engine off it goes back down). It sometimes does take ages to bleed the system. You can try repeatedly squeezing and releasing the top radiator hose. Also turn the heater to hot. I'm in Swindon, Wilts. Les Quote Link to comment Share on other sites More sharing options...
johnnycash1 Posted July 4, 2016 Author Share Posted July 4, 2016 yep water does go down if switched off before overflow, i'll keep trying then before I take it back off. I m in mid wales Quote Link to comment Share on other sites More sharing options...
Les Henson Posted July 5, 2016 Share Posted July 5, 2016 It's sometimes taken me an hour or more to get an air lock out. I don't think you need to take it apart again. Les Quote Link to comment Share on other sites More sharing options...
johnnycash1 Posted August 23, 2016 Author Share Posted August 23, 2016 ok update. I took head back off and a mate of mine had it skimmed. when it came back still 2 slight groves, like pistion linner groves in head above pistons 2 3. but put back together. runs but when revs build up noise like linners are slapping the head? dave Quote Link to comment Share on other sites More sharing options...
Les Henson Posted August 23, 2016 Share Posted August 23, 2016 Have you now had the head skimmed twice? Did you use just a new head gasket or a head gasket repair kit? Les Quote Link to comment Share on other sites More sharing options...
johnnycash1 Posted August 23, 2016 Author Share Posted August 23, 2016 les, put back no skim, and the bubbling, tried the magic in a bottle a £30 still no good, took head off n a mate had it skimmed, but he left it on doorstep have not seen him yet gone on holls, but two small groves avove intake side of piston 2/3 . I put back together on tick over fine, rev and there is a noise lick the linner is slapping the head? down to 20nm then 180 then 180 could I go anymore dave Quote Link to comment Share on other sites More sharing options...
Les Henson Posted August 24, 2016 Share Posted August 24, 2016 It's highly unlikely that pistons are slapping the head - your engine would be terminally damaged it it was. It. Don't overtighten the head bolts or they may well snap which may need sump removal. Les. Quote Link to comment Share on other sites More sharing options...
johnnycash1 Posted August 24, 2016 Author Share Posted August 24, 2016 could a linner be moving slapping the head? dave Quote Link to comment Share on other sites More sharing options...
Les Henson Posted August 25, 2016 Share Posted August 25, 2016 Highly unlikely. The liners should be slightly proud of the deck and are effectively clamped down when the head bolts are tightened. If one is moving with the head is on then your engine is wrecked. I would look for worn cam, worn/dished lifter(s), sticking valves,etc. Les Quote Link to comment Share on other sites More sharing options...
