well, before you actually start it. crank it with the plugs out until you get an oil pressure reading.

then when you start it, let it run for a while as you check for leaks and such.

when you start to drive, keep the RPM below 4000, under load, for the first 500 miles. then, gradually increase it about 1000 RPM every 100 miles after that. oh yeah, and definitely try to stay away from free-revving it constantly. i know it's hard, but ...

when you get to the 1000 mile mark, change your oil and filter, and it should be broken in.

^ Excellent advice.

Let me add to that.

Run some Lite Pre-Mix the first two tankfulls.

Change the plugs at the 1000 mile mark as well, they will likely be fouled.

Start it with dino oil .crankwith no plugs to get oil pressure, when it fires up keep the idle up about 1000-1200 rpm to keep oil pressure up. Do not rev it past 3000rpm for some time. Watch the temps check for leaks. Drive slow for 500 miles,change oil drive below 5000rpm with no boost for 500 more miles, if all is well then boost alittle and up your rpm.after every thing is seated well and adjusted 1500-2000 miles change to synthetic oil and go for it

Thanks,
the oil pressure sensor unit is on the rear intermediate housing (look for a round thing under where the oil filter sits) ... one wire connects to it.

An Autometer oil pressure gauge with 1/8" NPT fitting will thread right in where the stock electric oil pressure sender is.

Ok i gots some questions!!!

1) How do you crank the engine? I've always wondered this. Also useful for when i'm doing ATF treatment (not using ATF tho).

2) How do i check for an oil pressure reading? My haynes manual is in the mail as we speak.

3) Where should i be looking for leaks? Hoses, exhaust, intake, your mom? (jk)

4) Is a K&N oil filter good for a GSL-SE 13b 6 port street port? I'mna be running an upgraded high volume oil pump.

5) How come i love my rex so much? Oh wait.. nm i know that one...

Thanks!

Geoff

i'm not sure if i get what you're asking about number 1 ... the key usually works pretty well for cranking the engine ... hehehehe.

if your gauge is working, then just wait until it starts to move. if your gauge is not working you might take the oil filter off and crank it 'til you get a big mess, but it's better to use the gauge.

check for leaks at the oil cooler points, the oil pan, the radiator hoses, water pumps, etc. anywhere where coolant or oil can get out. the exhaust is not a big deal, (to be honest, i usually fire up my motor for the first time without the exhaust on it), the intake is a small issse because it might not start, but when i said check for leaks, i was referring to coolant and oil. i won't touch the mother issue ...

i'd still use a Mazda filter. there is thread with a link that directfreak provided, (it should still be on the first page) the only variation i might suggest is to see if the T2 uses a filter with larger capacity ... just an idea.
