The Badger Posted July 16, 2013 Share Posted July 16, 2013 So my defender is (allot of things but): Down on power (I tweaking the idle to help, but to no avail) Loosing oil (slowly) Loosing Water (Quickly, after about 90km its almost out) Got oil around the engine, where the gasket is On idle it sits at about 20 psi pressure So, does a 300 Tdi gasket fit on a 2.8 TGV? Does this sound like it is a gasket? Quote Link to comment Share on other sites More sharing options...
Ex Member Posted July 16, 2013 Share Posted July 16, 2013 It would be pretty strange to have an oil and coolant leak at the same time on the head gasket. Do a pressure test and look for the coolant leak. Check for coolant in oil and oil in coolant. Where is the oil leak around the head? Not sure on a 300TDI, but on a 200, there is only one oil passage on the right front corner. Edit: Having a look at a 300TDI, it appears to be the same. Looks like 8 coolant ports and one oil port through the gasket. Quote Link to comment Share on other sites More sharing options...
Tetsu0san Posted July 16, 2013 Share Posted July 16, 2013 Oil on the engine could be a leaky rocker gasket, but with the other things you are saying then it may be a head gasket problem. Is the water system presssurising? Is there not visible signs of water leak at all? To be losing that amount of water I would expect you would see something. Try putting some talc around the pipework and the header tank to see if you can see any streaks in it after a run. Bet thing will be to remove the head and have a look. I am not sure about the gasket fitting though, but I thought these engines were heavily based on the 300Tdi so I would imagine it will fit.

The Badger Posted August 4, 2013 Author Share Posted August 4, 2013 Im not getting any pressure, but, Yeah, ok. It's gotten easier to spot now that water is leaking from a seal somewhere around the head gasket at the front and pissing over the floor when the engine is hot. It's not the water pump seal, but it does just look like the head gasket but it's hard to pinpoint exactly where. Quote Link to comment Share on other sites More sharing options...
mmgemini Posted August 4, 2013 Share Posted August 4, 2013 Is the oil just under the head towards the front of the engine on the left side of the vehicle. engine ? If yes Check the inlet manifold for a broken gasket. Inlet manifold to cylinder head... As for the water....I haven't a clue. Must be nice to have such a great oil pressure on tick over..I struggle to make 14lb....... Quote Link to comment Share on other sites More sharing options...
The Badger Posted August 8, 2013 Author Share Posted August 8, 2013 Oil is creeping from that side. I have taken the air filter bracket off and that has revealed that oil has been leaking from there a little. It does not look like it's coming from the inlet manifold, but it does look a bit messy, I can take it off but doe I need to take the injector off to get to it? Almost got the head off but started a bit late and the sun has gone and the bugs are out. More investagation tomorrow... Quote Link to comment Share on other sites More sharing options...
TSD Posted August 8, 2013 Share Posted August 8, 2013 So, does a 300 Tdi gasket fit on a 2.8 TGV? Well, Since the bores are a different size, and so are some of the head bolts, I'd say no it doesn't. Quote Link to comment Share on other sites More sharing options...
The Badger Posted August 9, 2013 Author Share Posted August 9, 2013 Yep, my siv like brain now remembers, I can also thinking oh that a good idea I will fit it when it's not mostly -15, so I have ordered it and going to do it. Do I need to wire it up in any particular way in relation to the ignition / timing when it is on etc. I was thinking of putting it just before the injection unit? I don't know the minor differences between a 300tdi engine and the 2.8, but I think on the 2.8 the place where the fuel lift pump is different to on a 300tdi right? As the place where I think it is usually on a 300tdi is just covered with the air filter housing bracket. Anyhow, look for a head gasket, can't get hold of MDEngineering for it, so gonna have to look elsewhere, do you know who else one can be got from.

TSD Posted August 9, 2013 Share Posted August 9, 2013 Lift pump mounting is the same on TGV as 300tdi, and a 300tdi lift pump will fit. The only problem is that the priming lever usually fouls the injector pipework, so cut it off - you won't need it. I reckon the standard 300tdi lift pump can't keep up with the TGV at full throttle. I mounted an electric pump on the underside of the air filter bracket. That way you can keep the pipework unchanged, and mount the mechanical pump as a spare. Just wire it to the fuel stop solenoid, no special measures needed. It's the vacuum pump mount that is different. Don't know where else to source a head gasket, but you could try Prins Maasdijk in Holland, Old British Wheels in Canada, or any ford dealership that google finds in South America. Or try contacting M&D vie their ebay shop? Quote Link to comment Share on other sites More sharing options...
The Badger Posted August 9, 2013 Author Share Posted August 9, 2013 Got hold of them. After taking the head off, I found out that one of the glow plugs head had been burned off / or was crushed off by the piston. So with that in mind I am now taking the timing cover off to see if that is out a bit, just need the right socket for that tight big bolt... How to get that thing off Quote Link to comment Share on other sites More sharing options...
The Badger Posted August 9, 2013 Author Share Posted August 9, 2013 Actually, can I turn the engine over with the starter motor to try and do it as in this thread Quote Link to comment Share on other sites More sharing options...
TSD Posted August 9, 2013 Share Posted August 9, 2013 Just jack up one front wheel and put it in a high gear. You only need to remove the small inspection plate from the front of the timing chest, then set tdc with the slot in the flywheel through the drain plug hole, and check the pump timing with the end of a drill bit (9mm? Cant remember) Quote Link to comment Share on other sites More sharing options...
The Badger Posted August 9, 2013 Author Share Posted August 9, 2013 Iv'e gone and got it off now, well the bolt anyway, but not the pulley yet so I can still just look. Where is that inspection plate? Is it under the other belt tensioner. Quote Link to comment Share on other sites More sharing options...
TSD Posted August 9, 2013 Share Posted August 9, 2013 Right in line with the end of the injection pump. Could be behind the idler for the aircon pump if you have it. Quote Link to comment Share on other sites More sharing options...
The Badger Posted August 9, 2013 Author Share Posted August 9, 2013 Ah yes, that is behind the auxiliary belt tensioner, will have a look when the sun is out Quote Link to comment Share on other sites More sharing options...
The Badger Posted August 9, 2013 Author Share Posted August 9, 2013 With this - "then set tdc with the slot in the flywheel through the drain plug hole" That's the drain plug hole under the bell housing right, then do you turn the engine until you see a slot? As ever, slightly confused. Quote Link to comment Share on other sites More sharing options...
The Badger Posted August 10, 2013 Author Share Posted August 10, 2013 Timing out just a little, explains why one of the ends of the glow plugs what crushed off. Quote Link to comment Share on other sites More sharing options...
western Posted August 10, 2013 Share Posted August 10, 2013 pistons won't touch the injectors. the 'crushed' end will be heat damage from working cycles Quote Link to comment Share on other sites More sharing options...
The Badger Posted August 10, 2013 Author Share Posted August 10, 2013 Injectors look fine, just one end of a glow plug was crushed / broken or just worn out and burnt off. Quote Link to comment Share on other sites More sharing options...

Or is it that the fuel stop just triggers a relay? As for the mechanical lift pump, can I just blank off the inlet and outlet? Or should I loop a pipe between them?

I intended to put in a relay, but wired it up to test and it just kind of stayed that way I have a hose looped around the mechanical pump, just to try and keep it in the best possible condition in case I ever need it. No point having it pumping against a closed pipe. Quote Link to comment Share on other sites More sharing options...
The Badger Posted August 23, 2013 Author Share Posted August 23, 2013 Ok, I thought a loop on the pump would be better, so it just pumps through it's self a stays good, so thanks for confirming my suspicions. I was kinda hoping to avoid the relay as I don't know where to put it, but this pump needs a 5 amp line, so I was thinking of putting a fuse on it anyway then it got me thinking...

The Badger Posted August 25, 2013 Author Share Posted August 25, 2013 project update. it works... Eneded up doing a whole list of bits: New: Steering arm Uj's Steering box Track rod ends Steering Damper Head Gasket Injectors Glow plugs Air Filter Added: Electric Fuel Pump (great, primed instantly, cranked third go) Turbo Boost Gauge Swapped out rubber for some silicon hoses on various pipes Left to do: Rear left stub axel oil seal Change axel oil Change fuel filter Change oil Change oil filter Need some tlc I think.
