Mazda 6 2002 engine questions
New to mazda and the forum.
I bought my wife an 06 mazda 6 wagon at christmas which had some front accident damage. For the panels I bought another maxda 6 5 door from salvage auctions for the panels. My wife's car has been great. With a spare parts car hanging around, I just picked up an 02 sedan with an advertised blown motor and 9mths registration. The plan was, or could still be to swap in the motor from the parts car.On picking up the car it has a top end death rattle but still runs. My searches have steered me to the vvt. On looking at the vvt, externally I can see a round pin in the outer drum, which looks like it has something wedged in beside it, I'm assuming this is the pin which flogs out , also the exhaust cam has 1 side of the alignment slot broken away, so someone has been in there before although the advertised km on the odometer is 145KM. Plugs are all clean and the CEL isn't on. With a spanner on the inlet cam there is no resistance other than valve spring pressure to moving it through the range of the vvt, maybe this is normal with no oil pressure ? The plan could be to check I have oil pressure to the vvt and change out the VVT pulley, timing chain etc as required rather than change engines. Vlaves all seem to open and close, but not being familiar with these engines, unsure if there is more to the rattle.
Now for the easy questions,
1. how do I know I have a 2.0 or a 2.3 L engine.
2. Visually, the 06 auto parts car has coil on plug, and the 02 manual has a coil pack and leads. Any other obstacles in doing an engine swap other than componentry swaps?
3. is there a filter somewhere in the vvt oil pathway, or a quick way to check the vvt oil pressure and activator are working OK?
