Time for a minor (or major?) rebuild (LONG)
Well to make a long story short, my driver's side cam carrier gasket started leaking again this past weekend, to the point where I get a good plume of burning oil smoke at idle when warmed up. Add that to the fact that my driver's side head gasket has been seeping oil externally for awhile, and I think it's time for an overhaul.
The engine currently has ~100k on it, and I performed a minor rebuild about 4 years/~35k ago which included;
-timing belt/Laso water pump/tensioner rebuild + replaced idler and tensioner pulleys
-resealed oil pump
-front crank seal
-cam carrier gaskets/rear cap gaskets + all the front cam flange seals and o-rings
-intake refresh/replaced fuel hoses
More recently (~10-15k ago);
-oil pan gasket (cork) + motor mounts
-Porkensioner install
I'm sure I've forgetting a few things, but you get the general idea.
Anywho, my plan is to pull the engine if possible/feasible in my home garage and set to work pulling it apart. Before I get to that point, I am going to do a compression test to pinpoint any issues that require attention while I'm in there. I don't necessarily have any major concerns here but I want to be THOROUGH.
My main goals are to address the following. This list will probably grow as I think of other items to add to it.
-head gaskets/resurface head
-valve guide seals
-inspect/service valves and valve seats
-inspect cylinder walls for scoring
-water bridge gaskets/o-rings and thermostat, heater hose outlet elbow gasket
-timing belt/inspect water pump and Porkensioner
-inspect camshafts and lifters
-cam carrier gaskets, silicone rear cap gaskets + all flange seals and o-rings
-silicone oil pan gasket + possible stud kit
-replace cam and oil pump drive gears (worn past the point of re-coating)
-replace misc coolant hoses, heater valve, radiator hoses and coolant
There are some other odds and ends which need attention along the way, such as a partially stripped alternator mounting bolt hole, etc.
My first question is, pending results from the compression test, do I go as far as inspecting rod bearings, main bearings, cleaning pistons and inspecting rings?
I really want to be thorough in addressing anything that may need attention while it's all apart NOW, and avoid any further internal repairs for as many miles/years as I can. I have read from other member's experiences that the bearings usually do not require service for a good long time, but I'd rather inspect them now for peace of mind and before I throw lots of $$$ worth of gaskets and parts on top of them.
