Bent Big end engine bearing bolts

 

A customer presented a vehicle with an engine Knock, after removing engine and inspecting the bottom end of

the engine it was found that most of the bolts on the big end bearing caps where loose. On further inspection, it was noted that the engine had been dismantled for repair prior and appears the same bolts where used to reassembled the engine to sell the car.

Most manufactures these days will use one use item bolts only. What does this mean, It means that the bolts will stretch when tensioned from new, and once undone, cannot be re used as the bolt has already stretched to the point of no return and will never go back to the correct tension again.

So in this example it looks like this is what has happened, Over time the bolts work loose and eventually cause sever damage.

There is a mathematical formula for working this out. Known as- Torque to yield

When in DOUBT THROW OUT.

What is a pre purchase vehicle inspection?

A pre purchase vehicle inspection is a peace of mind check over  a vehicle prior to purchasing, This is not A Road Worthy but simply a check of all the vehicle components and systems to ensure you are not buying a  lemon. Its can also be used as a double back up to a RWC to ensure you are getting a good safe and reliable vehicle. Although you don’t have x-ray vision to look through the engine and systems, we methodically check over a vehicle based on our years of experience to determine the overall condition and reliability of the vehicle at time of inspection for your peace of mind.

When we do our inspections we ask our self one question. Would I buy this vehicle???

We give you our opinion and condition report for your to make your decision. We cant make your decision for you but we certainly can alleviate the guess work to make your decision easier.
