advice on engine overhaul or surplus ?

The noise sounds like a lose chain slamming on the sprocket. As oil pressure builds up the tensioner increase tension to remove the chain slack. Pudpod na yung ngipin ng tensioner nag nag aaply ng tension sa chain pag bumaba oil pressure. A bad bearing produce a continuous knocking noise.


Maghanap ka ng shop ng may ganitong tools:
Engine Stand
Micrometer
Dial Indicator
Torque Wrench
Torque Angle Gauge
Straight Edge
Oil Pressure Gauge

Hydrodynamic type bearing ang gamit sa engine hindi ball/roller type bearing. Nakalutang sa oil yung shaft.

Overhauled my 95 Hyundai Grace van with 4BDAS engine upon advise of my trusted and reliable mechanic and finished just today. I find the engine very nice after the overhaul compared to the 22 year old engine then. Breaking it in starting today and injection pump will be retimed next saturday. It took 10 days for all the work from disassembly, machine shop (4 days), buying of spare parts and assembly courtesy of my ever reliable and trusted mechanic friend.

Decided to have it overhauled due to noises coming from the engine and the temperature seems to be on the high side most of the time. Not on the overheating range but constantly on the high side especially when traversing inclines.

Got the van imported from korea around September 2007. Upon opening the engine, we found out that it had been top overhauled once. Now it was totally overhauled after 130K kms and 22 years of engine life.
