hi, my cargo is pretty sick! its a 1313,has a turbo fitted. i wasnt sure if the previous owner had fitted the ford 150 turbo engine in or just bolted a turbo on the side of the original 130. turns out it was the later after checking the block numbers this morning. it has the 7aa block which indicates its the 130hp ford. anyway, i used the lorry a fortnight ago to transport 2 of my vintage tractors and a caravan to a show, about 30 miles each way. on the way back i noticed it was gutless, more than normal. i unloaded and after about 45 mins i started again but had clouds of blue/white smoke which didnt clear until i drove 4 miles up the road. signs of the head gasket gone? i left it for a fortnight and when to start it yesterday, it started but was lumpy at first and still smoking white/blue. i pulled the dipstick and the oil is grey im an agricultural engineer so wont be a problem doing the head but do you think this was a random thing or caused by the turbo being fitted to a standard engine? i dont want to do all the work and have the head reconditioned if its likely to go again, i would rather just remove the turbo. according to the manual i have, the naturally aspirated 130 is 6200cc and the 150 turbo is 6000cc. but the turbo engine had different pistons and cylinder head. any advice greatly appreciated, im planning on removing the head on saturday as i need the lorry for a show in a fortnight. steve

It sounds to me it was the turbo you could try taking it off before you do any big engine work, there is a big diffrence between the turbo and non turbo the pistions are diffrent the timing is more advanced, the 150 engine hit max revs at 2400rpm, were the 130 went to 2600rpm, this is from the ford cargo manual,
the non turbo is OHV Naturally Aspirated 6224cc. Engine bore 107.2mm Stroke 114.9mm Compression Ratio 15,9:1 Valve clearance inlet hot or cold 0.38mm Valve clearance exhause hot or cold 0.38mm pump timing 23` BTDC
The turbo is OVH Turbocharged 5947cc Engine bore 104.8mm Stroke 114.9mm Compression Ratio 15,45:1 Valve clearance inlet hot or cold 0.46mm Valve clearance exhause hot or cold 046mm Pump timing 24` BTDC The injectors are diffrent hope all this helps, i would try taking the turbo off and then see how it goes.

thanks james, i m going to have the head reconditioned anyway and fit new gaskets and will remove the turbo when i put it all back together. that leads me to my next question, does anyone have non turbo inlet and exhaust manifolds kicking around in cornwall?
i dont think the turbo made much difference to the truck even when it was running fine so shouldnt notice much difference in performance. the lorry is only used for carrying vintage tractors to local shows through the summer so doesnt do any great milage or carry much weight.

I know a bloke in sheffield who has a cargo he is braking and he sents parts out so if you want his number let me know, if the turbo was conected as the timing would not be set right then the chances are you would not see any diffrence, i know my 150 turbo goes well but i think most of that is down to the gearbox as its straight thou final drive and the revs doing 60 mph are in the green were my old 130 horsebox was almost in the red doing 60 mph.

Unless the previous owner also fitted a turbo fuel pump, it wouldn't have made any difference apart from chucking more air in and probably making more smoke. It's the extra fuel that makes the turbo do what it does and without that the extra air is irrelavant. It would indeed eventually either pop your pistons, or as is looking to be the case, your head gasket (all, as has been said very different). A friend of mine once put a turbo on to a N/A Transit lump and apart from being extremely dissapointed with the performance, the only other thing he noted was that it blew one of the pistons within a fortnight... Edited to say: most turbo pumps (that are not electronic of course) have a boost module that works on a pressure/vaccuum principle, once the turbo starts to spool, the boost module gradually increases the fuel delivered by the pump.

i was going to ask if the turbo engine had some sort of boost control on the pump as like you said when the turbo spins up its forcing more air in with the same amount of fuel as a non turbo motor so in effect i suppose you are weakening the mixture and making it run leaner. when the engine was running good it didnt wiff a bit of black smoke and thats probably why. im definately going to remove the turbo. you couldnt notice any boost with the turbo either, i will miss the turbo whistling though!!!!

hoping to get the cargo going again tomorrow. had the head tested, skimmed and valves/seats recut/lapped in again. cost £200 but worth it in the end. plus £100 for gaskets etc. im doing the work myself so dont have any labour charges to worry about.
the head was bowed up in the middle and took alot of skimming to get flat again. the head gasket was blown between cylinders and waterways on pots 3 and 5. the gasket was also showing signs of blowing between pots 2 and 3, pots 4 and 5! no wonder i was down on power and difficult to start!!!!!
cylinder bores are excellent with no wear at all. will use the glaze buster before fitting head again though.
should be trucking again soon. will add some pics when i get chance and work out how to reduce the size of them!
