drum Posted February 25, 2018 Author Share Posted February 25, 2018 I took the tension off the fan belt and found a small amount of play on the water pump pulley. See also the water leaking in this pic. I'll see what the garage say, but I'll most likely put a new pump on before condemning it to the breakers yard. richardthestag 1 Link to comment Share on other sites More sharing options...
drum Posted February 25, 2018 Author Share Posted February 25, 2018 Brought it up to temperature again and not even a modicum of heat from the heater. Tried letting it bleed itself but no joy. It then started to overheat again after about 30 minutes. Link to comment Share on other sites More sharing options...
Guest Hooli Posted February 25, 2018 Share Posted February 25, 2018 Are these the engines where that have a plastic impeller that falls off the waterpump? I know a few did around this age. Link to comment Share on other sites More sharing options...
drum Posted February 25, 2018 Author Share Posted February 25, 2018 The internet advice is certainly to avoid the plastic ones. Link to comment Share on other sites More sharing options...
Guest Hooli Posted February 25, 2018 Share Posted February 25, 2018 I wonder if it's got one? lack of pumping due to that would cause overheating etc. Link to comment Share on other sites More sharing options...

drum Posted February 25, 2018 Author Share Posted February 25, 2018 One's water pump is fucked Sir. Can you not fire one on yourself?I will. I tried the motor factors on Friday but they were more than twice the price of online and couldn't get it before Monday. If I could have got one Friday or Saturday I would have had it on today. I booked in it thinking liner slip and wanted that checked out before spending lots. Link to comment Share on other sites More sharing options...
Guest Hooli Posted February 25, 2018 Share Posted February 25, 2018 If the head has to come off to check for liner slip then I think it'll be cheaper to put a waterpump on & see what happens. The Reverend Bluejeans 1 Link to comment Share on other sites More sharing options...
drum Posted February 25, 2018 Author Share Posted February 25, 2018 I'll speak to them first. Was hoping they could tell without taking the head off by pressure testing or something. If the head gasket is gone, the head will have to come off anyway.If not, I'll do the pump and see what happens. Link to comment Share on other sites More sharing options...

Des Posted February 25, 2018 Share Posted February 25, 2018 You'll easily feel if the pump impeller's adrift if you give the pulley a spin while the belt's off. drum 1 Link to comment Share on other sites More sharing options...

Isaac Hunt Posted February 25, 2018 Share Posted February 25, 2018 You got some superhicalls wading in deep on this. Good luck with the diagnostics and turns out to be just a pump and stat and coolant system bleed. Make sure you age the heater on hot when putting coolant in drum 1 Link to comment Share on other sites More sharing options...
DodgeRover Posted February 25, 2018 Share Posted February 25, 2018 If the heater isn't working and it won't bleed could there be some clogged pipes somewhere? Link to comment Share on other sites More sharing options...
drum Posted February 25, 2018 Author Share Posted February 25, 2018 Haven't looked at that yet right enough. I wonder if I can just take the thermostat out and run it like that.I've had a read and it's a big plastic job inline with the hoses so I can't take it out like the old style that sat in their own housing. I could measure the temp of the hoses on either side though with the infrared thermometer. I should really do measure temp at top and bottom of rad and other hoses to see if there is a blockage or air lock. Mrs6C 1 Link to comment Share on other sites More sharing options...
bsd Posted February 25, 2018 Share Posted February 25, 2018 That's my old one above, it pretty much had all of what you are facing with yours now. I replaced the waterpump, the heater matrix pipe, steering box, and then normal wear items - exhaust, brakes... it just needed some love!Still rate it and would again if I could justify one!By the way, i'm in Dundee and have the spanner and lock tool you'll need for removing the fan but more importantly, I have a car transporter that I'm happy to let fellow eejits borrow when in distress! Look forward to seeing you get this one sorted. cort1977, richardthestag, Exiled_Tat_Gatherer and 11 others 14 Link to comment Share on other sites More sharing options...
drum Posted February 28, 2018 Author Share Posted February 28, 2018 I braved the beast fae the east to pop this into the hospital this morning for its diagnosis. Got away from work early to hear the judgement and the news wasn't great. Annoying but not surprising. The doctor fed it some potion that changes colour if it detects hgf. It changed colour. So what now? Well I proceeded to totally fucking fuck it up, big time. I thought I would nurse it home, up the Glen. Better to have it at home for fettling instead of at my shed 7 miles away. Got about two miles before the temp gauge pinged into the red. I pulled over to let it cool down, threw some water in and set off. This time the gauge crept up to the middle if the dial and sat there. Not only that, the heater blew hot air for the first time since I got it. Drove all the way home assuming an airlock had unlocked itself but noticed the heater cool down with about a mile to go. Temp gauge still at normal so cracked on. Turned into my drive and it conked out. Had a look under the bonnet to find the cap wasn't properly on the header tank. I think all the coolant had gone. Gave it a couple of cranks but deed. Had to leave it where it came to rest. Gave it an hour and tried it and it started up first turn. Filled it with antifreeze and let it idle. No obvious strange noises and it came up to temp and sat there for 20 minutes before I switched it off. No heat from the heater. I think I'll still change the water pump and try some magic head gasket repair from a bottle. I've been pricing replacement engines.

drum Posted March 1, 2018 Author Share Posted March 1, 2018 Ah, fuck. But you did buy a P38. So..... when are you going to pull the engine apart?I might as well have a look before getting another one. The mechanic said you have to skim both heads? Replacement engines from about £450 on eBay.

Broadsword Posted March 1, 2018 Share Posted March 1, 2018 Bad news indeed. Failing all else, you do have a nice garden ornament there though. You can have a nice picnic on the tailgate in the summer and take in the view. Link to comment Share on other sites More sharing options...
John F Posted March 1, 2018 Share Posted March 1, 2018 I'd skim the heads anyway, if you're committed to a rebuild. Top-hat liners seem to be the cure, although tbh I'm new to this engine myself. Mine doesn't need attention yet... drum 1 Link to comment Share on other sites More sharing options...

The Reverend Bluejeans Posted March 1, 2018 Share Posted March 1, 2018 Steel Seal. Pull the stat out, pour it down the top hose and let it run for 30 mins. The fact that the heater blew hot for a bit suggests the pump is doing something but I'd still whip it out for an inspection. How much is a cheap new or good used pump? Steel Seal is 30 quid. Oh, and fuck repairing it properly. It's a P38. Fix that at great expense and the twat will bury you in something else. Before you know it you own a fucked £2000 P38 rather than a fucked £500 one. A fools errand. drum and Dave_Q 2 Link to comment Share on other sites More sharing options...
dome Posted March 1, 2018 Share Posted March 1, 2018 How conclusive is the HGF diagnosis? I'm guessing the colour change dye detects combustion gasses? If so then fairly conclusive I guess. Is a DIY head job that bad on these? It's rocker driven to no cambelt to worry about. Pop off the heads, quick skim and a new waterpump, back on the road for under £300.

DodgeRover Posted March 1, 2018 Share Posted March 1, 2018 If the £450 engines come with a warranty then maybe, if it's just well it was running when it came into the yard then no. If the heater suddenly started working it's shifted an airlock, that could explain where a lot of water went quickly - if it hadn't then run dry with the loose cap I'm guessing that may have helped things? drum 1 Link to comment Share on other sites More sharing options...
Exiled_Tat_Gatherer Posted March 1, 2018 Share Posted March 1, 2018 Hoping this /\ - as it sounds like a massive air lock has caused you a lot of trouble. The OMGHGF test doesn't bode well though. As D says, rockers - so heads off not such* a pain although a Davenumbers type skim wouldn't get them both matching unless you were spectacularly lucky - if punting back into auctionvilia then it may hold up long enough to be someone elses problem - at least we're all warned! It does look bloody spectacular in that scenery shot above though - heart would possibly* rule head for me I'm afraid. drum and richardthestag 2 Link to comment Share on other sites More sharing options...
