Thread: Disco2 problems

No Change... Phill @ Triumph Rover Spares Lonsdale's suggestion of removing the Glow Plug Relay did no good either...

Any other suggestions to try and trace this problem down?

injector washers.... check cam timing/ injector bump clearances and you may as well change the injector harness while the rocker cover is off. maf should be running at 100%

How many km on trans? And is the drive delay longer when left for several days as opposed to just overnight?

Hi all,

I don't think it's a drive delay from what I've read in the posts?? I think revird stated it just doesn't rev up if in park (Is this correct revird)?

I know if I leave my D2 (same year etc as revird) for a few days it's slow to take off or move but will rev no problems. Usually run through 1,2,3 D then reverse out does the trick! So my problem would be transmission related with oil draining out of the Torque converter or pump?? 278000km on D2

Can you post a video of whats happen to show us "what is exactly happening"

And if you can maybe ask the gent who helped out before to come and connect the Nanocom and do some logs, input fuelling and ......? (can someone else suggest another log to record?) You would need to have the Nanocom plugged in, turned on and ready, then let it idle, then start recording and try and rev etc like you normally would to replicate the scenario.

Cheers Lemo

Yep, the way I read it was a delay in throttle response, as opposed to a delay in drive response , it sounds like the engine can be made to rev in park / neutral because there is no load on it , aside from Maf related issues,
2 things that can cause this are injector washers, and / or cam timing ( especially if the head has been off and mistimed)
Yes Lemo yours does sound oil leak back related from an aged trans

Not criticising but how do injector seals or cam timing cause this issue?
Surely when the engine is warm the cam timing would be the same

Injector washers can let the combustion air through sometimes by the residual compression in the motor if the bad washer correlates to the cylinder on compression, it can also let combustion gas through when cold on first start which won't let an engine rev until pump pressure can purge / overcome the airlock , when the engine starts to warm up it can be enough to seal the copper washer again.
Wrt cam timing, if its set wrong ( usually retarded) when it goes into gear with cold oil , diesel , and atf it can struggle to overcome this until revved without the trans loaded up to get things warmed up , sounds strange I know but it really can be that critical and I wouldn't credit it normally , but I have twice found this problem, both times where some other person has done a bad job all round on replacing the head

Car has done about 330,000 not sure how to find out on the trans, don't know as the car is used everyday, but as far as I've noticed, it makes no difference.
