lowlancer Posted March 26, 2008 Share Posted March 26, 2008 Starting my first full blown engine rebuild tonight. Before I start ripping her to bits completely, what should I know? Should I mark certain things to ensure they line up all g when it's time to put it back together? Or given I'll be taking everything apart, does it not matter? Basically ANY advice at all will be choice, even basic shit. Quote Link to comment Share on other sites More sharing options...
treggo Posted March 26, 2008 Share Posted March 26, 2008 got all the required tools? Quote Link to comment Share on other sites More sharing options...
lowlancer Posted March 26, 2008 Author Share Posted March 26, 2008 Good point. List of weird tools I'll need to borrow please. Quote Link to comment Share on other sites More sharing options...
kyteler Posted March 26, 2008 Share Posted March 26, 2008 Depending on your plans for the engine, new head bolts etc as opposed to used ones which may snap on re-torque entry, is an old mitsi afterall (hides from Phil) Quote Link to comment Share on other sites More sharing options...
Dell'orto Posted March 26, 2008 Share Posted March 26, 2008 Follow the 6 C's of engine building. Clean, clean, clean, check, check, check. Make sure you've got all the tools at hand and all the bearings and gaskets too. Get some reassembly lube, don't be too jewish to use half the tub If you're not gonna reassemble it anytime soon, get lots of snaplock bags and label them with masking tape to keep all the nuts and bolts together.

macabre Posted March 26, 2008 Share Posted March 26, 2008 best advice ever with the snaplocks, label them exactly where they come from on engine makes reassembly 10 x easier. also mark the pistons and rods and rod caps so the stay together and round the right way ect. put corresponding marks on crank as well, i used a centre punch put 1 dot for 1 2 for 2 ect on bearing caps and cransk.

lowlancer Posted March 26, 2008 Author Share Posted March 26, 2008 That's the kinda shit I need^ Spose this is applicable to anyone so would be worth having a peruse for all those in my predicament Quote Link to comment Share on other sites More sharing options...
treggo Posted March 26, 2008 Share Posted March 26, 2008 piston ring compressor, valve spring compressor etc. Depends how extensive your going to be... Quote Link to comment Share on other sites More sharing options...
OSC Posted March 26, 2008 Share Posted March 26, 2008 yeah +1 on the labeled ziplock bags. same with pistons rods etc. if you dont know how something is routed take fotos first you will thank yourself for it later. otherwise tools wise a torque wrench and a piston ring compresser and a pack of ciggy papers is all you should need Quote Link to comment Share on other sites More sharing options...
fuel Posted March 26, 2008 Share Posted March 26, 2008 If you are reusing the original rods and pistons, label them so they don't end up back in another bore (specifically the pistons). Older 4G63s use normal head bolts, not torque to yield like newer engines do, so you can reuse the headbolts time and time again, but it might pay to measure them anyway incase they have been stretched before. For the sake of $40 for new headbolts, I'ld replace them anyway. Get a machine shop to hone your bores and check the crank journal sizes - it'll cost under $100 and it'll save alot of pissing around and it will ensure things are completely sweet, having said that we rebuilt a 4G37 with a three prong stone hone and electric drill and to this day it doesn't use oil and has good compression.

Gaz Posted March 26, 2008 Share Posted March 26, 2008 If you dont want to centre punch the rods etc then twink is a good option. Also may I know what the ciggy papers are for in the above list? Just curious? Quote Link to comment Share on other sites More sharing options...
QCADTA Posted March 26, 2008 Share Posted March 26, 2008 If you dont have a photographic memory sometimes taking some pics also helps just to jog the memory. Quote Link to comment Share on other sites More sharing options...
peteretep Posted March 26, 2008 Share Posted March 26, 2008 yeah i wish i took more pics of taking my escort apart, i dont even know where to begin with rebuilding it haha Quote Link to comment Share on other sites More sharing options...
Leebo3 Posted March 26, 2008 Share Posted March 26, 2008 I really domt know anything about these engines, but does it have a harmonic balancer/dampener? Of so you will need a special puller to pop the barstard off, can hire them or super cheap has them well, super cheap. But as what everyone else has said, stick the bits in bags and ladel them, even down to individual bolts pretty much, just makes everything so much easier in the long run. And take pics off all the stages as that will really help too. Quote Link to comment Share on other sites More sharing options...
Spencer Posted March 26, 2008 Share Posted March 26, 2008 yea also other than bags those cheap plastic organiser tray things are mint for bolts. And photos? its not very complex. Also can give the basic pointers over a beer someday Quote Link to comment Share on other sites More sharing options...
dumpez Posted March 26, 2008 Share Posted March 26, 2008 pretty basic one,engine stand they makes the job a hell of alot easyer. also a paint pen /twink pen is handy to mark all the bolts after they have being torqued,so you can do i final check and see if any are missed.

fuel Posted March 26, 2008 Share Posted March 26, 2008 front pulley on them is held on by 4 10mm bolts so you wont need a harmonic balancer puller. I haven't had to use one yet, soaking with CRC and tapping around the outside has always worked for me. Quote Link to comment Share on other sites More sharing options...
sentra Posted March 26, 2008 Share Posted March 26, 2008 here one i just learnt the hard way if your re-building a spare motor to then swap out, make sure your rebuilding the correct type of motor. and dont be nervous/scared measure shit 50 times and write down you did so, loosing sleep because you cant remeber if you torqued down some early-in-the-build bolt fuckin sucks. (and youl end up pulling it down and finding that you did actually torque it down and you just wasted 4 hours) 1 Quote Link to comment Share on other sites More sharing options...
cute wee gem Posted March 26, 2008 Share Posted March 26, 2008 Take stuff out/off slowly. I have memory lapses/probably singing along with the stereo and not paying full attention, pull it off then go "wtf, shit which way around did that little bit go?"

ProZac Posted March 26, 2008 Share Posted March 26, 2008 when installing/removing pistons put a small length of fuel or water hose over the big end studs, they have a nasty habit of marking the crank or bores otherwise. If your getting things honed and polished up again, not to much of a biggy, always do it for installation tho. Quote Link to comment Share on other sites More sharing options...
