Ok people got this e mail from a Surf owner via the web site, soon to register on here. In the mean time read his mail and see if we can help please.
Dec 1992 Toyota Hi –Lux Surf SSG-X EFI Turbo Diesel LN130 2LTE. I had 9 months trouble–free motoring (11,000kms) when one day she started to boil on the way home, Head gasket? Nope, corroded head plus two corroded liners & bores, scrap! I decided to import another engine (exactly the same type) and this was fully re-built by API. Absolute bugger to fit but, it ran perfectly for another 4,000km. Until I hitched–up my caravan (lightweight only 1100kgs) for the first time since the re-build when 5km down the road she cut out dead! She re-started o.k. but with a slight “camy” knock (like Diesel knock I’m told) Oil pressure o.k.,Coolant Temp o.k., ran fine except for the Knocking/tapping and a slight lack of power, but that may have been the way I gently drove her home!
Now, no oil was lost no coolant was lost, as (to me) it sounded a bit like Hydraulic lifters I flushed the oil out completely put new in, but no change, I drained 2lts of Diesel from the Tank, this was fine, I bled the filter, no muck, I bled each injector in turn, found no air and she ran fine on any three cylinders. I took the injectors back to the firm the re-conditioned them and they tested o.k.
She starts first pull every-time, ticks over perfect on both cold and warm, Oil pressure is exactly the same as since fitted. Other than the Knocking she does blow greyish smoke when revved! I finally got her booked into a Diesel pump specialist (the fella’s that re-conned and put new nozzles on the injectors) I tried to start her for the first time since Xmas (to put her on the trailer) but the batteries were dead. I charged these, put them back on Sunday, she started first pull, same story. However, once warmed up I gave her a couple of revs and the engine-management warning light came on
Perhaps I jolted a bad connection? But all the electrics worked fine before? And this light always came on with the key (as it should) then extinguished. Up to this point I was convinced my problem was Diesel pump phasing/timing, possibly something to do with the knock sensor system (which nobody seems to understand, or believe exists!) so I put all my eggs in the “have the pump professionally tested” basket, but now I think the problem could be electronic, perhaps ECU or Computer? As I can’t find any bugger who has the software in the U.K. to run the ECU or effectively test the management system I’m knackered! Up to now I’ve avoided contacting API as I’m scared of invalidating the warranty because I fitted the engine as supplied, all the ancillaries are my responsibility! (I did change everything except the Pump as this seemed fine!).
Finally, the only other thing worth knowing, because of the Surf’s overheating reputation, I fitted a capillary thermostat (to run the electric cooling fan at a lower temperature) a few days before my ill-fated attempt to go on holiday! I unplugged the connector from the loom (I’m not sure where or which Temp sensor fed this?) and took the power from one of the batteries via a correct relay, locating the adjustment switch on the viscous fan shroud (which works fine). I doubt if this is relevant, you’ll know if it is?
Sorry, my tale is so long-winded but without the vehicle to look at, you’ll need all the detail, or you will be as lost as I am! (Perhaps).
