As we all know sometimes scrappies hand you 100k km plus engines that deteriorate with certain passage of time. And sometimes engines are good too. Depends on how you know about things. My engine was good but, issue i faced was timing adjuster broke on the way to muree once i somehow managed to reach muree and then came back. This thing brought valve missing in my car.
Due to timing mismatch, the cams weren't provided with oil flow so they seized Slightly.
I was somehow dragging the car.
And it's compression dropped to 140-120-130-138
Anyhow i planned for working on it and was saving for it.
My estimated expenditures were around 15-20k
But they slightly exceeded because people from engineering works set there own rates.
When the head was lifted up, it appeared a cylinder 2-3 were cross. Head gasket was blown.
And when inlet valves of 1 cylinder were meant to be opened the contrasting inlet valves of cylinder 2 were to be closed but they were left open.
I built the head, valves grinding done, seats were replaced so were the tapets, gats and valve stem seals.
Second issue was smoke, what we saw was almost all pistons were dancing inside the block when they were moved left right. Good rings and pistons never allow this dancing of pistons.
Anyhows i bought new cams from mushtaq. They were 10/10 cams, i pulled them from a head mushtaq had in his go down also with cam caps.
Gave him 2500 rs.
Then i was in a hope he'd be having pistons or a good block assembly but both the things were unavailable. The block's he had were corroded.
So now finding the Rings was the headache. Kiyani autos said a big no for 80mm rings. The one he had were 82mm but the top ring was very thin, which my mechanic said is inappropriate.
Anyhow after a slight struggle we know the secret about the Rings, lol which I'll release to the person having this project done. As I've done research on this myself. As when you'll go finding QG18de rings, you'll hear a big no from everyone.
Moreover the piston pins were loose too and causing loud tak tak sounds while revving the car.
So pins were changed too.
Gasket was made of carbon sheet.
To cut the story short built it very nicely mashallah.
25k were spent nicely to get almost a new engine.
Now the engine is on running process. As my mechanic strictly told me not to rev or heat it until 1500-2000km.
Alhamdulilah all was done good and quality parts were added up to the engine.
So here goes the whole project.
So guys don't worry QG18de can be built too.
Mashallah getting 190-195psi pressure on all cylinders.
Project consumed 2 days.
Saturday Sunday night the car was ready.
