5m-ge future engine mods?

[mechrider89]

hahaha good one! I'm highly doubtful its the switch, I'm thinking its the control module. I'm going to talk to my journeyman friend and get a second opinion before I go any farther on the wipers.
I was going to send the head in next week but since I just got my 3 speeding ticket today I might have to wait a little longer.....

[mechrider89]

Well I got some big news......... I found some hidden rus.......let me rephrase that I found a lot of hidden rust. Its only paper thin in a couple of spots but its still scaring the heck outta me. I'd hate to just let this car go on the way side while its still very save able........ so I guess I have a decision to make on what I'm going to spend this years safely bonus on. Either put 1500 toward de rusting the supra to prolong its life or put the whole 2k into the talon project........suuuuuccchhh a hard choice. On a brighter note I have been offered a deal on a set of ST lowering springs from another supra owner, would drop the supra 1.5 inches and I should be able to get them for 240 shipped. Oh and the head is finally at the machine shop getting a "face" lift.

Well since I had the day off I figured what the hell why not work on the supra. So I got working on taking the head off, started at 12 pm and it took me till 3pm to finish. I thought that's not to bad a time for it being the first 5m I've worked on, big thanks to Canadianbak'n for posting the TSRM link for me (along with all the other help ).
To late to take it to the machine shop today so it'll be going tomorrow instead. When I got to taking the cylinder head off it was the moment of truth for me, and boy did it go in my favor! The pistons and cylinder walls are in great shape, can still see all the cross thatching from being honed. The top end looked just as good as the bottom end as well, I feel my spirits being lifted slightly now!

Will take some pics in a bit for you guys to look at.

Block got a pep talk....its a dsm thing

little before machine shop pics


all my cylinders looked like this so that's a plus





Forgot to say that I did a compression test before cylinder head removal and here's the results (dry test only):
#1- 170 psi
#2- 167 psi
#3- 170 psi
#4- 140 psi cylinder 4 and 6 are where I could see the HG had failed, cylinder 4 had the biggest failure
#5- 170 psi
#6- 150 psi

Just cleaned up parts and such today and measured my head studs, some had about 2mm stretch in them I just hope I can still use them. Also found out the whole felpro seal kit I bought is missing a lot of gaskets which is a huge let down. To add to that my cam towers need some serious machining looks like shavings got in between the cam and races in the towers, but the lobes for the rocker arms are perfect.


Worst one, felt litterly like sand paper, yet the cam wasn't to bad.

Figured well I had the top of the engine off I'd also take the time to give the block and engine bay a nice scrub (its filthy), get some before and after pics of that to.

looks good keep up the good work!

ok well since I've been very lazy with the updates I'm just going to plaster everything up.
I got my head from the machine shop last weekend and was impressed with the price, it only cost $189.00. They resurfaced it a 0.006 ,cleaned it up, pressure tested it and installed new valve seals. But when I got to unwrapping my head (lol) the clean job was complete shit and still had rust, old gasket material, and carbon in the exhaust ports. So I spent and extra 2 hours cleaning it more instead of bolting it up and I was pissed off about it. Also got them to look at my cams and cam towers and they said they were in great shape. But continuing on I was waiting on parts till this monday so I couldn't really assemble much but now I'm at the home stretch. I had a little trouble timing the engine but I got it right after an hour, painted up my valve covers to (not my color of choice but its all they had) hope you guys like it. I've got everything back on and bolted up except for the oil pressure regulator, vacuum lines, accessory belts, clutch fan and shroud.
with out further ado here's the pic's:

Will take a pic tomorrow morning quickly to show where its at right now.

looks good and nice work on the valve covers.

thanx man!

Well I finished her off today and added my coolant then went to start it........it wouldn't start!
So I checked for spark and had that, checked fuel and i have fuel to the rail then I rechecked my timing and all was good. so then I started checking over everything else double checking everything was connected and all vacuum lines were on, once again everything checked out. Tried to start it again and noticed it was back firing out of the intake, which means it has to be timing! So I checked again and again still good......I'm at a lose.

how about dizzy timing? and have you done a compression test? sucks if the motor is dry and no oil pressure has been built, but you could always prime it, retime it then do a compression test..

thats ruff man, i hate when that crap happens and have definitely suffered through it.
