Suspected head gasket failed 3l v6
« on: 12 April 2013, 15:00:17 »

Re looks like I'm stuffed Thead and seized tension pulley and aux belt and leaking radiator

Just got it all back together after putting in new radiator pulley and belt

Start and seems to be running ok on all cylinders and don't seem to be running too bad
temp seems stable to
But coolest is pussing out under car and trickerling off sump

It not coming from anywhere near what's been touch ie up frount by radiator

And steam from under back of plenuim thing
Hbv is fine checked so is heater hoses only done heat matrix few weeks back

Is it worth look anywhere else for a leak or do you guys thing it is defiantly the head gasket


As if it a top end rebuild I'd beyond me and I'm running out of cash fast




So I'm guessing it the head gasket

Take the plenum and inlet manifold off followed by the lower sandwich plate to have a really good look at oil cooler plate/thermostat and coolant bridge area.

They are all very strong possible areas that can leak and give the very symptoms you are describing

Could a overhead from a failed aux belt cause that

Worth checking the oil cooler plate & coolant bridge area, not unknown for one of the pipes at the back to split and pish coolant all over the place.

Was the Car / Engine being used after the Aux Belt problem, if so, how long for?

Plenum off, along with inlets, so you can see right into the V.

Join or block the 2 pipes that you removed from throttle body to remove plenum.

Pressurise the coolant to about 8PSI (blowing hard into one of the pipes above will work) - coolant leak will be obvious.

Extreme overheating is a worry, but do tests I suggested to locate leak.

If HG has failed due to overheat, inspect heads very closely

Hmm,Im 50 50 on this one,it doesn't take much to do a HG on the V6 without the Water Pump running, I know from experience when the Ex killed off one of my Plods after driving it for 5 mins when the water pump pulley threw the Aux belt!

Does it sound completely normal when you turn the engine on the starter?.

Im up the road from you if you want a second opinion, might not be the right one, but 2 heads are better than one and all that. ;)

Lets face it people-any engine especially v6 mig will do H/G's in if no coolant-no brainer really-so but its true-I had that a few weeks ago and was quicker/cheaper to change engine on mine(243000 miles) anyway

thing there aint no smoke there was at first but it wa pissing down thing was just warter in end of pipe after a min no smoke but now thers no smoke to speek of

i think it probably is head but there a hell of alot of coolant pissing out form out side rather than inside of engine

but im going to try anyway with crossed fingers as i would like to keep for now if i could

it got to be worth a try if its not leaking there

and it head im going to cut my losss and move on
and scrap it as i cant break it as no where to keep it off road and break it

unless any one wants to make an offer for spares or repair



back arches were due to be done as starting to rust but its only got 105k on it iv had it since 40k suspensions been done done heat matrix just had new front wishbones for all German parts 4 mouths ago

just had new back box and two new mid boxs and pipes
one of the guys of the forum done my water pump and cam belt kit not that long ago for me

and now a new radiator and aux belt and pulley

crank sensor been done since i had and i done the abs ecu already

only thing wrougn with other than this was driver heated seat element dead couple of l bulbs need changing back arches now need doing and a small rust bubble on bottom of back door

With plenum and inlet manifold off, look carefully around coolant bridge.  If its p*ssing out likely to be rubber hose from coolant bridge to HBV (the "curly" one).  Flex it and look for holes around where its clamped to coolant bridge.  Also check its not leaking from the coolant bridge seals, although wouldn't expect it to p*ss out fron here unless they are completely gone.
Also check oil cooler plate and thermostat housing while stripped.
