Good one Tel or should I say Victor Pratt ;D ;D ;D ;D ;D ;D ;D ;D


Take the P mate wouldn't dream of it

Sounds like you already emptied your bladder down the block anyway ;D ;D ;D ;D

Now ...... If I said any of this I would be inundated with Pm's complaining

Oh I get the Pm's Dave but I just ignore them and treat um as Fan mail

right after stripping this dam engine for the 3rd time i still dont seem to have any pressure.ihave cranked the engine for 20ish seconds 2or3 times and still nothing. there is oil comming out of the feed pipe when you unbolt it and crank it there is also oil comming out of the pressure relief valve. i have also spent about 45mins blowing the block out with a compressor and it appears clear as i get air comming out of the oil pump resess i just cant seem to get my head round this.any more ideas before i go totaly insane. maybe even another metro block if anyone has one.dirty one would be fine ill just send it to victors carwash. the other thing i dont understand is that i dont seem to be able to get a pressure reading from gilberts old engine which was running fine prior to removal as i should be able to get a reading just by cranking and all i seem to do is drain the battery

[oldgit]

Tel are you using an oil pressure gauge? does it work?
Does oil light go out?
Do you get oil pumping out or just a dribble?
With rocker cover off do you get oil up to rocker gear?

[katentel]

jim oil gauge tested in matts car and sidewalk so ok there not connected to light at present but thats what brought it to my attention in the first place, oil is just dribbling and dont appear to be getting to the rocker

[delly]

personally i don,t think the starter motor will spin the oil pump fast enough to give you an oil pressure reading


normally when you are starting your engine the oil light stays on until the engine starts this indicates that no pressure is obtained till the pump is at full speed

i may be wrong

having lots of experience of cold start problems recently I can tell you that on my pickup I need to crank then engine over on the battery for about 20 secs before the standard (7 or 14 lb?) oil pressure switch cuts out.

N.

[oldgit]

You should get some pressure when cranking over engine for 20 sec or more.Having read though all post again and bearing in mind dean has had a look and tryed most basic stuff,only other thing I can think of is wear in crankshaft journals .Think Im right that this is a new engine to you.Have you seen and heard it running?

[katentel]

i have had this engine in the car and running for about 20 mins it was only when i went to turn it off that i noticed the oil light was still on. it seemed to run ok and sounded pretty good. however im going to strip it right back.this time it looks like a total job!! arghhhhh

[monkeyjim]

As you know Dean spoke to me about the basics and we are all happy on that front .

Cranking the engine with a healthy battery and the spark plugs 'out' , the oil pressure light will go out, providing all is well .

Has it got the 'o' ring seal fitted between the gearbox and the block ?.
The oil strainer sits in the bottom of the gearbox
Attached to strainer is oil pick up pipe .
Oil pick up pipe has a flange 2 bolt fixing where it bolts to internal rear wall of gearbox .
That oil pipe is fed by a hole in the gearbox located on flange at rear of box, biased toward the clutch end .
Sure you know all of this
The flange I am talking about is the one you fit the gearbox to engine mating gasket to .

If there is no 'o' ring in the recess on the gasket flange at the drilling that feeds the pick up pipe you will have no oil pressure .

Other than that I would take the entire engine to bits and check crank oil feeds , make sure the shells are in the right way and basically build it again from scratch . Use a older Haynes manual as last time I looked at one which also covered injection models I found that it did not go into in-depth detail of older manuals and the gearbox was hardly covered at all .

Hope you get it sorted .

It should do normally, if you take the plugs out as Dave says

decieded to go and see mike at sussex engines yesterday and explained EVERYTHING to him he came up with a few suggestions which i have tried alas to no avail,so decieded to take the block in to him to strip,inspect and rebuild.this afternoon he phoned me with the news that the damage was caused by the failure of the original oil pump,see photo's,this had caused all sorts of damage to the bearings shells and crank what i thought was creaminess in the oil actually turns out to be the remains of some parts that have been ground down to a fine powder.hopefully ill have this engine back early next week then a mad rush to get gilbert going for brooklands, not only that poor katy is suffering withdrawals as she has now bee over 2 weeks without her beloved gilbert. thanks to everyone for all advice and matt and dean for all hands on help

[oldgit]

Soz to hear that tel

Sounds expensive,hope all turns out OK.



At least it wasnt the internal wash that done it

[katentel]

hey at least gilbert will have a good clean engine. and yep this is gonna hurt
