Mechanic Apprenticeship

Posted 07-06-2010 at 01:10 AM by Tristen
workin' for this dude who's gonna teach me everything he knows about cars. the great thing is that he fabricates pretty much everything he does.

today i looked at his model-A with the mid engine and then went on to sand and paint the chassis of the kit car he's gonna teach me to drive.
It's getting a MGA engine soon, and it needs some suspension work... the body prolly needs some help too, but i haven't seen that yet.

Camshaft Installation Pre-Shim

Posted 06-27-2010 at 09:09 PM by Gairloch
First I want to acknowledge that my cams and caps are amazingly carmelized. I took them to work and ran them all through the parts washer but that didn't help matters at all. I'm going to have to take them to a machine shop and have them hot tanked to get them clean I suspect. I need to get the valve covers dipped too so I'll take them all in at once after I have the shim numbers.

Parts:
  • Cylinder Heads (Left and Right)
  • Camshafts (1 intake and 1 exhaust per head)
  • Camshaft

Assembling the valves

Assembling the valves is pretty straight forward. My biggest challenge was in locating a valve compressor that works. Most of the models I found required more room than is available in the 1mz cylinder head. I ended up settling on a compressor that bolts down where the valve cover attaches and has a bar that runs the length of the head.



Components needed are:
  • valve
  • spring
  • valve keepers
  • spring

Lapping the valves

Posted 06-16-2010 at 03:03 AM by Gairloch

First step for me in prepping the heads was to get them dipped and decked. Being on a pretty tight budget I chose to disassemble and reassemble the heads myself.

Visual inspection shows that the oil races are all in good shape. The valve guides all measured in spec then it came time to lap the valves.

Tools needed:
  • Valve grinding paste
  • Valve lapping tool

The process is pretty straight forward. Stick the valve to the lapping tool by the suction cup...

Evolution of a 1mz install

Posted 06-16-2010 at 01:37 AM by Gairloch

So I've got this '91 MR2 that seems to be hungry for engines. So far it's eaten 2 5sfe's at race tracks during HPDEs because of oiling issues. I refuse to believe that an MR2 doesn't want to be driven hard so I'm going to run with the theory that it's hungry for more ponies. After careful consideration I decided to attempt to sate it's hunger with a 1mz swap.

Now because of the fact that I've had 2 engines fail on me I knew I was going to need either a crate motor or one that...
