@spitfire, Ya are quite a perfectionist type of a person. In khi mechanics overhaul 4k in less then 3-4 hours. But their engines last I guess quarter of what your engine will do...

Thanks...

[spitfire]

another....

@charterali...
yes ,you are right dear that I am a perfectionist.But this habit creates a lot of problems too...:)like,the colour of Spitfire is still under consideration for last about two months..and many many more things.But one cant help inbuilt nature..
After I decided to overhaul this engine,I spent a month or so in collecting genuine parts(which are hard to find now)like pistons and rings(at about three times price of "art pistons n rings").genuine valves,genuine timing gears+chain(gears were not needed at all but I could not help my nature and found original a very hard way),genuine timing chain tensioner(hard to find),genuine/original oil pump(only rotor kit was enough but again....)The only thing I could not find genuine was gasket set.....But again I managed to get genuine valve seals.......and so on...

and another view....cylender bolts are there too..

[spitfire]

[spitfire]

Before going any further, work done so far was checked by our "Chief Engineer"......(spitfire junior)...

[spitfire]

And he found something wrong there....

[spitfire]

After we fixed the problem..lolzzzz he again checked it and gave us green signal to go ahead...but he preferred to check final torque of bolts himself...lolzzz...

[spitfire]

next item was pistons......
old ones with piston pins and locks.They were in perfect shape and could be reused by using "cylender sleeve" os standard size..Piston rings grooves were in perfect shape...I was amazed to check them in this condition after 250000 KMs on the clock...

[spitfire]

Connecting Rods were given to Machine shop for the replacement of small end bush (the part which is attatched with the piston with piston pin..."gudeon pin")and obviously setting of big end pieces (the part which is attatched with the crank shaft).....
another view of old pistons with all parts..notice that they are in pretty good condition.....I think reason is just single hand driven with very regular oil change using best oil available......and no abuse....

[spitfire]

And new pistons with rings in grooves....
In genuine rings upper most is steel and lower were cast iron....But the one used in routine like "ART" or other replacements...there is "NO STEEL RING" all are cast iron...resulting early wear and less engine life..

[spitfire]

New pistons with connecting Rods and gudgeon pins in place..

[spitfire]

Another view of new pistons/rings and connecting rods..

....And another view........
