87 Nissan D21 - Z24 - Timing Chain Replacement Questions
So I got this truck I'm falling in love with about 3 months ago for $700. I guess it had been in the person's family I got it from for 28 years... last owner was a 18 yo kid that tore it up pretty bad. I've already done a bunch of work to the truck and have found it's pretty easy to work on overall... I like it. So it started rattling the other day and a mechanic told me it was the timing chain tensioner. I've everything pulled off the motor up to the crank shaft pulley. I need to get the right size socket tomorrow... 27mm I read somewhere. Anyway I've got a couple questions about this whole process.
1. Is it true that I would have to raise the entire engine to change the oil pan gasket? (2WD) I think mine is leaking (although it may be the rear main seal. I'd like to go ahead and change this if it dosen't involve hoisting the engine... I don't have a hoist, or means to get one over here.
2. I need to replace all of the gaskets I'm guessing. Water pump, front cover, oil pump, valve cover, distributor... what sealant do you reccomend? and it it necessary to replace all of these gaskets... (I already have the waterpump gasket) blue silicone good enough? and do I need an oil pan gasket even if I don't remove the oil pan? Chilton manual says something about cutting away the exposed part of the oil pan gasket and replacing it.
3. This is the first tme I've gotten this far into an engine. I'm probably being overly careful, but how do I make sure the #1 piston is at TDC? Maybe this will be obvious to me once I actually get the front cover off. I'm assuming I can rotate into position if neccesary with the truck in neutral?
4. Any easily avoidable mistakes when replacing the cam sprocket, crank sprocket, tensioner and guides? Honestly... I like working on this truck, but it is my daily driver... and I don't want to have to go through tear down and assembly twice.
5. If I keep everything straight... what are the chances I won't have to adjust the timing. I've never done that before. (I do have a light now though so I plan on learning at least how to check the timing)
Ok, enough questions... any advice is appreciated... once again this is a 87 nissan d21 2WD with z24 engine.
