View Full Version : How to swap heads quickly.

Actually, the belts, and pullies plus the cover to the timing belt takes quite a bit of time. Also remember you have to compress, and insert a pin in the timing belt tensioner. Every time you undo your timing and reassemble it the risk of a timing belt failure goes up. not every dsmer has removed their power steering and air conditioning, is you think you can do all of that in 20 minutes, then you sir, are a machine. So I would estimate that this saves closer to an hour + worrying about the tensioner failing pre-maturely.
So no, this saves more then 20 minutes :)
Curious to see what the total time on your head swap ended up being with this method.

Maybe we should video tape it, make a race out of it. This time it took a little longer because some of the bolts broke off in the turbo, but think about it, valve cover, arp nuts, arp studs, thermostat housing hoses and electrical connectors, throttle cable, then LIFT

Oh. Well assuming the bolts didn't break (that stuff happens regardless), what would be your estimated time on this? I know on a 2g dsm "book time" for a headgasket job is: 7.1
1g headgasket book time is: 6.8
Both figures are via Alldata for awd's with a/c.
I have used the "bungy cord" method several times. It definitly saves time but I have a feeling Nightrider and Pushit2.0 could do the whole job the right way in an hour sooner than the rest of us taking the shortcut method.

Mark showed me how to do this when we did Kevin_1G_drummer's HG on his 1G, I used the same technique each time I did HG swap on my evo. First time however, I dropped a bolt down in the timing belt cover and ended up pulling the tbelt half apart anyways. Re-doing a t-belt easily adds two hours and a lot of PITA to a HG swap. Just to not have to pull the water pump pulley off alone makes this worth it.
I like your tool, very nice :D

I've done it both ways. In the end I just got really fast at tearing down the timing belt side and setting the timing belt (I've done so many I dont even know the count, same with many members on this forum).
The "lift and yank" sort of way to do it very quick, but the risk of dropping something, bumping something, etc just isn't worth it if someone is paying me to do it. If it is my car and I just did the t-belt stuff, I might entertain the idea, but then most of the dsm's I've owned don't have intake's bolted down to long, a/c systems that work, etc...so all that is out of the way.
Still, anytime you get to invent a tool, is a good day in my book :):whoo:

10mm ratcheting wrench and a 10 mm fixed end wrench, Take the ratcheting one and spin it towards the fixed, the fixed will "tighten" the other will loosen up. Then its a game of : :ring: for the 4 bolts as you spin the water pump and remove the bolts.

Good idea on the bug hideous tool.
We older dsmers roll zip ties and paper clip thingys even cheap cam blocker from harbor freight.
Congrats though if it makes ur work go faster then it's worth it

looks very much like an overcomplicated version of the vice grip method.
but kudos for you guys for making your own tools. :)
This tool is fast you can have your head swap done in minutes(leaving the manifolds attached), and there aren't any flying vice grips or bungie cords involved! No one likes those!

That's awesome, what a time saver!!
