1st sr20det startup....oil and other good stuff to use

[ROOSEY]

okay so i recently just rebuilt my sr20det motor pretty much stock compression just forged internal. what im wondering is what kind of oil do you use with the first startup and any special liquids or anything else that i can add to the oil to prolong the life of my motor. ive done searching and found that obviously use 5w30 or 10w30 depending on the climate. but can i add anything to the oil or gas to help the motor on the first startup, other then a fresh tank of 93 and whatever type of oil i decide to use.

thicker or thinner oil for first startup? or just go with what i was to begin with some 5w30 or 10w30?

thanks guys any help would be greatly appreciated!

Just get some brand name 10w-30 to flush out the assembly lube and metal shavings from break-in. Change it and filter at 50 and 500 miles then goto your long term oil.

I second that. I used pennzoil 10w30 changed at 50 miles then again at 500 then full synthetic Royal Purple with mobil 1 filters.

ok sweet thanks guys that helps alot! so also change the filter after the first 50 miles too along with oil?

[nismoman]

Absolutely, critical.

[S14DB]

Yeah, All the shit left in the block from the rebuild washes out in the first 50 miles. The assembly lube will dilute into the oil. But particles like metal shavings will end up in the filter and will clog it up fast. The 50 is more to get the assembly lube and packaging waxes and oil out of the mix. There are some particulates in the engine from machining but you never know how much. The filter change is just a cheap insurance.

At 500 the bearings and rings should have broken in. There will be a ton of shavings in the oil and filter from the burrs and edges wearing down.

Get or borrow a filter cutter and pop those two filters open. You'll be amazed at the junk in a new engine.

ya that totaly makes sense i'll deffinitly do that then. whatevers gunna keep this motor going is what ill do. id hate to see a newly remachined built motor that ive put tons of money into go to crap cuz of my ignorance and a oil filter i didnt change haha :bash: thanks a ton you all have been a huge help!

is there anything else i should know or do? im planning to start it up for the first time this week.

just follow what was stated above, its exactly what i did for my engines first startup.

just make sure you put in some fresh gas in the car if its been sitting for more then 60 days. after 60 days gasoline tends to go stale.

and make sure that when you first start the car , let it run for atleast 20-30 mins. there WILL be smoke but dont worry , thats just rings seating and gaskets sealing, its nerve racking to watch but its all part of the process.

[ROOSEY]

okay ill let it run then for sure. also ive heard you SHOULD NOT EVER rev your engine when your first breaking in the rings and starting it. idk if thats true but it sounds good enough for me to believe. and im deff putting new gas in also. the smoke thing is good to know ill still be worrying though haha

Rent this, Melling MPL-101K1 Melling Pre-Lube Engine Oiler (http://www.jegs.com/i/Melling/689/MPL-101K1/10002/-1?CT=999)from), from Oreily Auto parts. It's pretty expensive ~$190 but you get it back when you return it. You'll have to rig something up, fitting wise, to make it connect to the oil pressure sender port. Once you get it all hooked up you can make oil drip rapidly from the cam oiler tubes. This will only put oil in the engine. The back flow valve in the oil filter will prevent oil from getting to the back side of the oil pump so you'll still want to prime the engine by cranking right before the initial start.

[ROOSEY]

okay awesome ill look into one of those also!

[ROOSEY]

and just for the record when i prime it i turn the crank clockwise right? not like a honda where you do it counter clockwise?

[S14DB]

The B, D, or H series is the only engines in recent history that runs counterclockwise.

[mct3351]

To prime the engine, remove the spark plugs. Crank the engine in 5-10 second intervals, waiting about 20 seconds between to not over work the starter. Do this until the stock oil pressure light extinguishes or a few psi of oil pressure is achieved on an oil pressure gauge.

oh wow im retarded i was thinking doing it by hand i gotcha now!
