Problem solved. Worn valve guide.

I think iv already found that problem as well the water pumps on bmc engines are known for trouble this one appears to be leaking and has a good wobble on it. Where the fan belt goes arround it Liam

Just to clarify things, the st2 is in my own boat, and was very badly maintained so iv gone through and rebuilt it, the posts I have put up on here have been to help me fault find on a few things that were wrong with it, from when the fuel pumps had been set up after being reconditioned. I have been doing mechanics for rather a long time know, and I always like to hear other peoples opnions on what the problem might be, as evrey one is diffrent and diffrent sujestions, after having alook at the bmc, it appears to have bent an exhuast valve. As it is slightly off set to the rocker arm, and also has alot of gunk in the rocker box exactly where this one has bent, problem diagnosis, so then problem will be fixed. Liam As o have also stated above I just do mechanics as a hobby and to help people out. As I have all the tools and kit. But I akways like to hear other peoples thoughts on what things might bee. Evrey day is a learning curve with stuff, and evrey problem can show many diffrent signs

hi there got a BMC 1.8 it seems fine in tickover hardley any smoke, put it in gear it starts knocking also starts to run hot after about 30 to 45 mins. could this be either head gasket, or big end bearing gone. many thanks Liam

The engine had a fulk rebuild new crankshaft main bearings etc, so evreything was stripped all the casings shot blasted etc and powder coated and so on, fuel pumps and injectors sent away for overhual, it runs very clean till you Hit three quater throttle then its just all smoke, iv checked the racks a fare few times they dont appear to be sticking, the idle spring? Is this where the two racks connect to the second pump?

It's not theres a bearing gone on it, they saidbto us could be a week or two.

Hi Tony, iv set the govnor up per what the manual has said, iv re timed the engine its had the pumps and injectors overhuald. Ever scince its never idled right. The engine has had new cylinder heads piston rings, crankshaft bearings etc.

Would the engine run if timing is one shim or two out tho, smoke is minimal starts up straight away etc, but is ticking over way to fast but when looking at rack its virtually all the way shut?? And when pulling the stop over it barley moves rack mms for it to stop engine. All linkage moves freely first thing I checked, Tony.

Right, iv set the gov up on my lister st 2, but its still ticking over way to quick when you go to turn engine off the rack is almost fully back as well I mean its mm. But if you open it up and control it on gov by hand it ticks over lovley this is with the morse disconected. You then stop engine and re start and back to square one again. Any ideas and sometimes has a habbit of running away too. Both pump marks are spot on with the sides of the housing so im baffled know.could retarding fuel pump timing move the rack to a diffrent position

I've bought a complete new pump for this,bi know they can be tricky to fit and a spanner on the end of the gearbox to rotate it until the pump engages and then just slides on. Alot of people have told me that they use engine oil in the gearbox, I thought it was ep80-90 to be used? Liam

Hi, thanks for help. All sorted turned the key two turns she started straight up. Next job new oil pump on gearbox to fit old one has seen better days.

Just had a crankshaft of them for my st2 brilliant service almost evreything in stock and when they say itl be there its there couldn't knock them at all

Iv got the manual or a manual. Anyway. Thabks for your help going to spill time it today. Thats how tight it is thanks

Ah okay, whats the best way to shim the heads and what distance do they need to be pumps are alighned correctly I shall have another go at spill timing. The enginenis also alittle tight nothing major gussing thats due to the new bearings etc. Its had crank regrind bearings camshaft bushes, rings valves pumps etc iv done the full works

Hi, iv recently done a full rebuild on my lister st 2 and I mean evreything, tried firing it up today would only run on one cylinder, the number one cyl wont fire, took the injector out number 2cyl cranked it over all I got was white smoke unburnt fuel. I have two shims on both pumps can the pumps be shimed diffrently or have to be the same. Its definitely a fuel based problem. If the clearences between heads isnt correct can this cause it to not fire Thanks Liam
