Tapping becomes more noticable once the engine is warm
What does tappet bleed down mean? will I need to renew?

While I'm sorting my cold start problem I've noticed a tapping noise coming from the plenham
good oil presure and the engine runs well once started
anyone had similar?

changed fuel temp sensor - s/h spare
changed water temp sensor -new lntermoter
still would not cold start smelt of fuel - flooding
disconnected fuel pump and she started up on the fuel in the engine then died
reconnected pump and she started
runs and starts when hot
what to check next ?

After 1000+ miles on rebuild it turns over but will not fire up
checked fault code reader- clear
spark at plug no8, but soaked in fuel when removed
any ideas??

Engine starts and idles o.k. Runs well initially Car will pull steadily but open the throttle fully and it loses all power, misfires (?) untill you come back off the throttle. After the car's run for a while it cuts out and dies, leave it a while (cools down ? ) it'll start and I can drive off New 8...

Yes,pipe comes from top of throttle butterfly

On my 3.9 EFI I've got a round metal disc attached to the dizzy( next to the thermostate housing ), believe this is for the air pipes One pipe comes from the throttle body, which side should that go on ? Should I have a pipe on the other side of the unit? If not should this be left open or blanked o...

Replaced the oil pump gears but I'm having trouble getting the Mocal take off plate ( for remote oil filter ) to seal.

Fitted a new gasket with a light smear of sealer, but it's still leaking oil between two of the fixing bolts

Is there a trick to getting these to seal ?

May have confused myself here

May have a SD1 chest and P6 water pump, chest stamped ERC 0036

In which case new SD1 gears should be o.k ?

Just been looking on the internet to order new oil pump gears, came across a problem. I'm running my old P6 front chest and remote filter from my old 3.5 engine, now I find there are different length gears, and ends(dizzy drive) The gear dizzy drive I have is male, fits straight into my new 3.9 dizz...

Oil pump/gears looks favorite then as it hasen't been changed.

How does scoring of the base plate affect the pump ?

As I have a remote filter the base plate is the take off plate, should I get that resurfaced or get a new one ?

Thanks guys

Everthing inside the engine is new, except oil pump gears ( just remembered), con rods and reground crank

Oil is Lucas 20/50

Started to run the cam in on my 3.9 v8 rebuild When it's up to temp, running 2000 rpm, oil pressure reads around 25psi, we let it idle and pressure drops to virtualy nothing, but the oil light didn't come on. No horrible noise from the engine, but I should have more oil pressure, surely Where to sta...

Thanks for the advice
Looks like the water pump gasket is leaking too , so it's a strip down tomorrow.

rebuilt 3.9 v8, ready to be run up.
slight coolant leak from gasket /head running down onto the block under no 1 cylinder.
Tried a short bolt in outer (unused ) bolt hole, no difference.
Any ideas or is it a strip down and new gasket ?
