Bought a beautiful 94 Pathfinder 4x4 Auto, drove it for 3 weeks and it jumped time, sheared pully off crank. Had already replaced over a dozen little things and installed 33in Toyo Open Country MT tires....so I decided to go all in.
94k mile motor for $880 from Car Monkeys...and $1500 to have it swapped with parts and labor for new timing belt/water pump on new motor and gaskets, misc stuff and the labor spent on the old motor...


So....BEFORE I have the mechanic drop the new motor in, is there anything you experienced guys would do now? Upgrades, things to replace/check?

Looking at $3400 total, to have a 94k 1994 with 5 year warranty on motor. Probably should have walked away, but I love this little 4x4.

Obviously, I would have a new timing belt installed. Weak areas of these engines are the exhaust manifold studs, rear main seal and engine oil pan's rear lip seal. So, I would check for broken exhaust studs, replace the rear main seal and R&R the oil pan and reseal it. It's also a lot easier to replace that #6 spark plug when the engine is out! As far as the timing belt, if you haven't got a new one already, I'd go with a Gates Timing Belt and Component Kit with Water Pump from Rockauto.com, along with new front cam and crank seals and thermostat from Nissan. Drive belts I would go with Bando from Rockauto or genuine Nissan. Any ignition system components I would go with NGK or genuine Nissan.

Well, the replacement engine looked like crap, a lot of dry rot, so I ended up doing ALL the seals, even pulled the heads. I replaced every vac hose and fuel hoses. Spent WAY more TIME and MONEY than I wanted to, but I'm back on the road and should have another 200k miles to go.

Now it's time to break out the nippers and get these 33in Open Country MT tires to fit better Shocked
