Mazda BT 50 & Pickup TrucksWhile Mazda may not be known for their trucks, they have always produced quality reliable trucks for both hauling cargo, or simply crusing. BT 50
Probably had a problem with valve keeper on that cylinder and dropped a valve in. I recommend you pull the cylinder head and fully assess the damage. You'll probably need a remanufactured head at least but with that mileage, more likely need a new engine.
If I were in your shoes I'd be considering a Kia swap on this truck. The body looks decent so its worth it

Another head is only $400 and Im into the truck for 1500 so no big deal.
Sure my son will crash ot into something before the engine takes a dump again.
Aside from visually inspecting the piston for damage, what else should i look for?

Scored or cracked cylinder walls.
If you put a new head on a high mileage worn bottom end it’s a recipe for high oil consumption. Also, it’s possible for rod or bearing damage from the valve dropping in

That is a B2600i truck......and the EFI 2606cc G6 Mazda engine in it makes more power & torque than an EFI 1998cc FE Kia engine.
Also, the G6 engine is a timing chain engine (no belt) along with twin balance shafts also driven by a chain......the timing chain may have let go and caused a valve to contact a piston.
Regardless, these are definitely good engines, and worth rebuilding......I have rebuilt several of them and they perform superbly!
One thing to realize, the "Oil Pump" is also the front timing cover, and it ain't cheap (around $300.00) but definitely needs to be replaced when rebuilding these engines.

Point well taken. So how much $ do you have in that 2600i rebuild total?
