What Ive been reading is mixed thoughts on filling with the engine on and 'pumping the air out'.

After thinking about something said earlier and putting 2 + 2 together, im wondering if the air is getting trapped in the back radiator.
What I was saying in an previous post, since I took out the spring from the thermo the air in the cabin goes from hot to cold to hot to cold etc, so now im thinking air might be getting trapped somewhere in that area.

I think I will flush the water tomorrow and refill with the engine running and see if that makes a difference. Im not actually taking the car to Dublin now, gonna used the missus' dinky car (fiesta) to be on the safe side but still want to be able to do more in my car than go to the shop lol.

Everyone must be on holidays lol..

Just an update on my progress so far..

I put in new spark plugs today. The misfire on #3 was definitly a bad plug, but now I think their might be a bigger issue because there was oil all over the plug (i'll post a pic shortly).

Picking up later today:
Plug leads, water pump & belts.

Im not interiorly convinced the thermostat is the issue with overheating, since I removed the thermostat from the housing its still overheating, not as quick, but still doing it either way. So gonna change the water pump because im sure that's on it way out like everything else on this badly maintained car.

The oil on the plug is a bit worrying but im hoping its just something like seals or something. I did a few searches but like everything else, there is mixed views, some say Vanos some say seals, others say replace the engine (don't think I will be doing that one haha).

Any ideas??

Cheers

Hi Guys, its been a while, so just done a quick flick through to catch up

Drop on your oil on plug issue, it wont be Vanos our M43's doesn't have it! so that's ruled that out. Now i remember having this issue with a old car, i had replaced Valve Cover Gasket (or rocker gasket which ever you like to call it) and O Rings around the plug cavities and this resolved the issue, it's DIYable and about and 60-90 mins mate. I can't see it requiring new engine! The cheapest route would be to do VCG and O Rings. Then check the Spark plug housing which you know had the leak a couple of weeks later to make sure its not oiled.

Hey Shaun, hows tricks?

Well thankfully its just a diy job, me likes getting dirty under the bonnet Ill have a crack at that next week maybe.

Today its water pump day, just picked up a new one so gonna pop that in later and also retest my thermostat. I dont think I had the pot hot enough the last time. My new diagnostic thing says it opens at 105c. Im sure I didn't boil the pot hot enough to get 105.

What im thinking is the water pump may be the type with the plastic fan and have read alot about those deteriorate and the blades break so the water is not getting pushed around as good. So I would presume if the water is not flowing properly then air is not getting pushed out thus over heating.

Like you've said it could be that the plastic impeller has failed in the pump... I checked mine last week as i have a leak and I found whoever changed it last put a metal one in there. The problem I'm getting is trying to get a good seal, ive changed the O-ring but its still leaking a little

A little gasket sealer on the pump where it presses against the engine might sort that. There could be a little dirt stopping ir from sealing properly. Although the leaflet I got with mine says the oring will seal it, im probably going to put a small amount of gasket sealer on the flat surfaces anyway.

When I put it back the first time I noticed that besides the o-ring seal there wasn't much of a flat face surface area to make a seal so i did put gasket sealant on there... going to take it out and try again...

I just changed mine and made a balls of it. One of the bolts didn't go in right and seems to have made a new thread on the engine lol... 3 seems to be holding it just fine

The old pump looked a bit mangled looking on the inside. Was a lot of crap built up on parts of it. Probably would have needed to be changed soon anyway.

My bolts felt dodgy too on the way out but that was mainly due to some rust at the bottoms. I nearly screwed up the thread as I used one of the bolts a the jacking bolt but it was fine in the end. I took the pump out again today and put a lot more sealant this time as i could see it had leaked from the bottom. If this fails I'll get a new pump ...

hmmmm, when I put it like this it kinda makes me even more determined to bring her back to life!!

This is a list of what I want my mech to look at. We are going to make a project of it and work on it between us over the next 2 or so months.

Im sure we will find a few more bits not in the list, but have a gander anyway.
