Thread: 1991 Rangie. BAD Engine knock.

Definitely a knock.
Surely noone in their right mind would gring one Bigend journal because tha knock is definitely louder under load or accelleration as would be the case with a Big End.
Not having done the job myself, I cannot be sure that the mechanic gauged every slipper when he fitted them either.. How much attention did he pay to checking the conrod / Gudgeon movement or for that matter the piston skirts by pulling each piston down to the bottom of the bores and having a good look. It's all unknown to me.
I will give richard a ring this morning and see if he can shine any light on the fault as a lot of the parts came from All 4X4 Spares, Just not happy about the Holden Lifters that were put in instead of genuine rover ones.
Back to square one I fear.
Shirley....

I agree Duane,
I wish he had have left the lifters alone, it may be the start of another nightmare.
I am looking for a good low K motor or even a wreck that's been rolled but have not yet found any leads that would give me what I am looking for.
The Truck is so clean and tidy with do damage anywhere, otherwise I would just trade it in, wreck it and get another unit. God it's hard on a pension.
Thanks Heaps Luv,
Shirley....

Ive been getting mixed messages here

You are now running gas

(Did this noise come in after you flipped from petrol to gas or vi-versa)

"The noise comes in under load"

Shirl ... are you sure it's not a case of pinging or a rattle (when under load) ....
as you keep saying it's all around the top of head

The timing of dizzy might be out or not set right .... if so // Good news

Check the timing

Mate, I've got an injected 3.5 with the computer and all from a rollover for$300 if you want it. Pick up from Nowra, approx 2 1/2 hrs south of sydney.
This is out of a 1991 Disco, already pulled from the vehicle.

Shirley, call Murray at Jag and Rover Spares in Kelvin Grove in Brisbane. He imports cars and wrecks and quite often has a few in stock, prices vary pending on the number of kms they've done. Outlaw from the GCLRO bought one from him recently

Shirley, I see you live at Wyee.
If you like you can bring it down to Avoca and I will have a look at it or should I say listen to it.
One thing you should look at is if all the exhaust gaskets are in position. If one is not tightened it can make a noise that can be mistaken for a knock.
The Holden lifters should be OK.
PM me and I will give you my contact details and if you want discuss suitable times.
I am not a mechanic but I do all my own work and have rebuilt a V8 and done lots of lesser things.
Regards Philip A

Shirley from now on only take it to Triggs at Toronto for work that needs doing.They are a family owned company and serviced my partners disco and we have not had a problem with it ever.They will sort it out for you. Pat

Ditto on the exhaust gaskets. I had this on my 3.9
I thought I had a big problem, only a $10 gasket
