    Default Performance after Complete Engine Overhaul.

    Hi Everyone!
    I have Suzuki Khyber 1999 Model. It was running smoothly without any problem for the last 08 years but now for the last 4 or 5 months it was blowing and consuming engine oil. I had to add 0.5 litres of Engine Oil after every week to keep the level. The vibrations in the engine were also increased.

    So I took the car to the mechanic and after opening the engine, he said that complete engine overhauling is required as the gap between pistons and cylinder walls will not be covered just by changing the piston rings. Today was the first day and he has given me three days time and an estimate of about 20-23k Rupees for the complete engine overhaul.

    But he was saying that after the overhaul, the pick of your car will be decreased because before overhaul, it was burning engine oil which increased its pick.

    Guys I am a bit confused about this statement. What do you say about that? I mean what is the purpose of spending 25000 Rupees when the car's pick is going to decrease?

    @speedster_101
    What quality/price seals you got?

    Was the gearbox opened to change shifter seal?

    Do cam, crank and rear man seal need engine to be removed to replace them?

The smoke was occasional. So in Oct 2015, I changed all the seals (cam, crank, rear main seal), clutch n pressure plate, clutch bearing, timing belt, timing bearing etc. Gear shifter seal was also replaced as gear oil was getting leaked.
    The leakage for both (engine oil and gear oil) was stopped after that, but the car was still reducing engine oil. I wanted to get the engine overhauled in winter, plus I had to complete my MS thesis before that, therefore I waited till January 2016.
    if the cylinders are ovalled and the crank is damaged along with the cam and rockers - the above mentioned oil is what killed it.

    A well kept suzi G10 engine blows out its valve seals - this happens due to using low quality seals and running the head hotter than normal. Before teardown a compression and oil pressure test could have shown you accurate diagnosis that if your engine actually needed an overhaul.

    In my experience - as mentioned above the usual failures were simply valve seals and tappet cover breather. Both of these lead to huge oil consumption and blue-white smoke.

    @Xulfiqar is it possible to have a noticeable increase in low end torque if the valve lash is kept a little looser than spec? I have read online about people performance tuning through valve lash on flat/roller tappets but no idea if they ended up burning the valves.

    So is it a good idea or are there other ways to increase low end torque?

    Car is khyber.

    loose tappets will clatter a lot and will wear out very quick. The valves wont burn as burning happens from valves not closing fully (jammed tappets) - Low end torque is not simply a tappet or toon job.

    Go over everything on the engine, adjust to factory specs. Including distributor (if the centrifugal advance is sloppy the engine will feel like a dead honda 50 pulling 4 milk bottles)

    I once changed the cam and crank seals and for that engine was not removed.
    But in Oct, 2015 the engine was taken out of the car, gear box was separated and then it was sent to machinist. I do not know how he changed the shifter seal. But the mechanic told me that he has changed two seals. Shifter seal and top seal.

    The following three pictures were taken in Oct 2015 when seals work was carried out.

    The camshaft and rockers were perfectly okay, however cylinders needed boring. The size went to 1.00 from 0.50
    About crankshaft, the main end and big end bearing went to 0.50 size from 0.25. Does it mean it was damaged?
    The Thrust collar/washer new and old size is 0125.
    Why do you think that 20W-50 oil damaged the engine? It was old API SG, suitable for these engines.

    50 weight is quite heavy. 40 will be good. Tried and tested. Delo in these old flat cam cars and they last very long.

    Actually the user manual of SA-310 recommends API SD, SE and SF. These oils are not coming anymore.
    Havoline is API SG but its 20W-50. The thinner oils are API SM/SN.
    Last week I bought 2 packs of SGO Premium (3L and 4L), its API SG. I think its the only 10W-40 oil coming in API SG.

    I know. This oil and Delo are the options, but delo really cleans out engine very well and has more zddp then this oil.

    Delo comes in 15W40 and its fine to use all over a year. Delo has better additive package then this oil. 15W40 or 10W40 are good for these old suzukis

    The metal pipe connected to water body was full of rust, reducing its diameter. We bought a new pipe along with other spare parts on first day but it was of Suzuki Margalla. Mechanic was reluctant to go and exchange the pipe but I said no way I am putting back the engine with the old pipe. Finally he went and exchanged the pipe.
