Looking at a used frontier with a vg series 6 cylinder at a garage, and they mention it was a client’s truck, the timing belt went and they didn’t want to pay. The shop took it, fixed it, and is selling it. As I understand, the vg is an interference engine, so if that belt went so did a whole lot else. Is this correct? If so, keep looking?

UPDATE: engine smoking, smelled liked burning oil. Nope

If it is a interference engine, your pistons and valves are buggered, non interference generally means the pistons and the valves can’t make contact, so it’d be a case of resetting timing and fitting a new belt.

But since it’s a garage that has it, I’d bet it’s a interference engine, hence why they haven’t fitted a new belt and sold it already.

You can get lucky sometimes and the piston and the valves might have managed to avoid each other but interference engines typically do a lot of internal damage when the timing belt goes.

Sometimes you get away with only a few bent valves needing replacement. It doesnt always mean disaster necessarily.
