Assalamu Alaikum Everyone
I need help regarding a TLC. I don't have any experience at all so will be thankful to get assistance.
Recently got an auctioned TLC LJ72. Its engine was dead so replaced its engine with 'kabli" upon the suggestion of few mechanics. The issue I am facing is High RPM / engine rattling on 90-10 KMPH. Cannot tell exxact RPMs as RPM meter is not working at the moment. Is there any way to reduce RPMs on highway.
Toyota LJ72 1991
Engine: 3L (2800cc diesel)
Gearbox: G40 (5th gear was added already, As per mechanic)
4x4: Not Working (No shaft in place)
Rear Diff Ratio: 4.88 (39/8)
Tyres : 205/80 R16
Engine Oil: Using Delo Gold Ultra 15w-40
Its genuine engine was 3L and the replaced one is also 3L but noticed that replaced engine is from Hiace. Concluded this because its engine oil filter is on driver side and installed filter is 90915-TD004 which is usually known as Hiace filter. Need advice to lower its RPMs on higway. 95% on road use in middle Punjab. If it will allow, a trip to North once in a year.
Best Regards,
