Is my 2.7 shagged?

**Ranga** · 11th April 2020, 07:01 PM

I know it's probably hard to diagnose an engine fault over the internet without much confidence, but here goes...

Basically it was running fine with about 230,000 kms on the clock. Previous owner was driving it and it starting making a horrible engine noise and stalled. They managed to restart it briefly before shutting it down. It's sat unused for about 6 months.

Today, a mechanic (non-LR) tried to do a quick diagnosis. They managed to get it started after turning it over for about 10 seconds, but it sounded sick (a bit of a knocking and scraping sound and not idling right at all) . Had his foot to the floor, but before too long it stalled. I wasn't too keen on starting it at all, so didn't try again. I thought the fact that it actually did start might be promising, but as per my typical motto, "expect the worst and hope for the best". So, I'm expecting the motor's shagged and needs replacing.

Apparently 2 common failures are the oil pump/timing belt or broken crankshaft. Would either of these allow it to still start? Anyone game to have a stab at likely problem/s, and repair options/costs? At best this might see the road again, at worst it will be broken and parts sold (or sold as is) to try and recover some costs.

Finally, any decent mobile mechanics Brisbane north side that would be able to come and have a gander?

I would have thought if the pulley had snapped off the oil pump then the engine would not have re-started as the belt wouldn't be able to drive anything. I would assume seeing as it started, albeit only briefly that you have possibly got a broken crankshaft . I seen a V12 MTU run very roughly mind you , but still ran , with a broken crankshaft which had some very good mechanics scratching their head until they dropped the sump .

Either way it doesn't sound good and you are likely putting a territory engine in it as a guess..

hope you didn't pay top $$ for it.

remove the timing belt cover and have a look

I think I got it at the right price - probably equivalent to what I can sell the aftermarket accessories for. I would rather get it running again, but given it's the EU3 spec, I'm not sure if the common Territory motors are a straight swap.

I wont be a snapped crank - if it was broken then you wouldnt be getting any drive to the front of the crank which in turn would not turn the front timing belt pulley = no camshaft or high pressure fuel pump movment.

That was my comment re the V12 ,the crank snapped clean and once 1 cylinder fired the engine managed to run albeit very badly , admittedly has double the amount of cylenders, but using the same principle , if 1 cylinder fired on the TDV6 , with the timing belt still fitted then it may possibly be why they could get it to run for 10 secs.

All assumptions of course , but was more thinking that the timing belt must still be connected as the engine did fire. only way to be sure is a lot more investigation.

Initial thoughts would be the crank - the front could in theory still fire however it could be a myriad of things.

Drop the sump and check.

My reply to a post in my other thread. Probably best I keep it all in this one, as the other one refers to an engine swap (which may or may not be an option).
