Hi people i need some help on this one, my engine siezed up after running for only 7 seconds, the engine was brand new so ive taken it back to the company who built it and he's saying its due to to much fuel, the problem is the gudgen pin siezed in the piston. He is also saying it has damaged the piston and the bore?? my question is : is he feeding me a line? is there anyway this could do that damage???

 

Absolute Bollox.
You would have to thin the lubricating oil with fuel massively to have virtually any effect on that Gudgeon pin IMO.

Theres no way you could do that kind of lubrication damage in 7 seconds.... absolutely no way, sorry.

 

Is that you sitting on the fence Stu????

 

I agree with Stu...

wrong clearance on the pin to piston would be the reason it seized lol

Not unless the bores were totally filled with fuel.
Would cause some serious damage, probably wouln't even turn over though.

 

pacificzetecturbo,

They are feeding you turnips mate!!

Did you build the engine or did you have it built by them?

 

Thats fookin bollocks!! who is saying that?

 

No they built the engine, i dont like slagging companys off untill i know there at fault. so untill then..........oh ok it was burton in essex!!

 

Its a pin clearance issue for sure.

Or some coont forgot one of the clips!


This is the problem with people DIY building engines, they almost NEVER check the clearances on the gudgeon pin.

I can quote you mine all to the nearest 10th of a thousandth of an inch, whoever built your engien should be able to do the same

 

Burtons a, you sure you didn't totally fill the engine with petrol then try and turn it over??

They are a very reputable engine builder.

 

To be BRUTALLY honest, i reckon it would last more than seven seconds in that scenario too

 

They cant argue with that! if some1 of Stu's caliber is syain it!

 

IF you are correct about the 7 seconds thing then there is no doubt that it was the wrong clearance, if it had a decent clearance even if you forgot to put any oil in it wouldnt punch the pin out through the block that quick as it would still have the lubrication on it from them assembling it and would run on that for a little while.

 

We had then sell us the wrong stuff for an engine saying they were matched - wrong pins.....

Total cowboys LOL....they wouldn't replace either.

 

So few people seem to realise that you have to check new pins etc for clearance, they assume just cause its an expensive set of rods and pistons and pins that it will all just work.

The difference between "building" an engine and just "assembling" one.

 

Just to clear up a small matter i think burtons have a good name and i wouldnt want doubt it, there is probably loads of things it could be and maybe it is my fault i just dont expect to be taken round the houses getting there. Tell me the problem, back it up with some evidence and if its my fault ill pay for it if not then just put it right, im gagging to get it running for the summer! its just a piss off that its happened.
The truth is i was turning it over for about 10 mins without the coil lead on, then put that on it started but didnt run properly it ran for a second then stopped, it was the firing order so i changed that started it reved it to about 2500rpm it squeeled then stopped. That was what happened, im no engineer but surely somthing caused it? i just find it hard to belive it could be too much fuel.

 

turning it over for 10 minutes with the coil lead off?
first question why?
second question how many startermoters did you burn out?

 

To build up oil pressure and all on the same starter motor, i have to add it wasnt continuesly, it was in spurts!

 

Why on earth would you turn it over for 10 mins like that?

Wonder if the revs never got high enough for the pump to generate pressure and it didnt get oiled then.

suddenly the plot thickens a bit compared to "running for 7 seconds"

 

And did you see oil pressure on the gauge?

 

Well heres the silly bit: i dint have the clocks connected

 

TBH mate, i dont see that you have much of a leg to stand on here.

You CERTIANLY bore washed it unless you disconnected all the injectors.

And you possibly turned it over non stop with no oil pressure.


Its one of those situations where you should just accept that you shouldnt be working on cars

 

Ive already accepted that, i sell them not fix them i leave that to the proffesionals,.....im quite good at breaking them though!!

So what your saying is that it could be down to fuel??

 

No im not saying its down to fuel alone.

But pumping 10 minutes worth of fuel into the oil certainly will NOT have helped.

Then combine that with it may have not been turning over fast enough to get the pump going properly (as i suspect that you didnt even remove the plugs to ease it turning over like you should when trying to build up pressure on the starter?)
