9 thread heads?
All the remans come with the latest 9 thread heads.
9 thread heads?
Someone confirmed they aren't the Zoler (sp) that came in the originals engines. Remans use a Mahle piston. We still don't know if it's a larger PTW though.
My thought's are if they bored the remans 20 over and still used the exact same piston size as before wouldn't we get more PTW? Big IF...
Car is officially running again only thing left in question is my air/fuel ratio is a little off... it sits around 15.8-16 at idle. I've sent a datalog and email to Eric @ brookspeed to see what he thinks
No they wouldn't use the same size pistons, in a .020 overbore. It would sound terrible and wouldn't live long. Way too much clearance.
Congrats!
please see my break-in procedure. I researched the hell out of proper engine break in.
Started by using 5w-30 Conventional oil with a bottle of GM EOS. I primed the engine through the oil pressure switch port using a bug sprayer and a hose barb. I let the engine idle and warm up while I bleed the power steering and cooling system, also checked for leaks. After about 10 mins I drained the oil and changed the filter. Refilled with the same valvoline and EOS, test drove the car. Got to some open road and started in 3rd gear around 1k rpms, when 1/4 throttle to 4k, then let the engine compression brake back to 1k. Did this 4-5 times, then 1/2 throttle doing the same, then 3/4 throttle doing the same. Did this for about 20 miles.
Drained the oil and changed the filter. Refilled with Joe Gibbs break in oil (conventional 5w-30). I did the same procedure on the way home. I'm going run this oil for another 200 miles and change the oil and filter to conventional again. Ill will change the oil and filter every 500 miles until I have about 4k on this engine. Full syn 5w-30 will then go in.
I first ordered the RP Break in oil, but at the time it was on back order. So I decided on the Joe Gibbs stuff. I have been checking my JLT oil separator every 500 miles or so. I have only accumulated .5 oz in 4k miles!!!! That is a good sign there isn't much blow by, so it appears my rings have seated properly. Check out this site I used as a reference and modified the procedure a bit:
Break In Secrets--How To Break In New Motorcycle and Car Engines For More Power
Good information in that link. I also found other engine builders who wrote pretty much the same thing about proper ring seating.
Just thought i'd get this going in the "proper" section of the forum.. basically i installed an autometer lunar series oil pressure gauge a couple months back.
When the car was idling i noticed the oil pressure gauge on both the autometer and lunar series gauges were dropping to zero at idle. I thought it could have been an electrical problem.. until i hooked a mechanical oil pressure gauge up to the engine and saw the same result.
In the end, it sounds like the old motor has a spun main bearing. I recall when i was accelerating around 2,000 - 3,000 rpm there was a some what of a "marble" sound through the throttle range.
Heres the car..
And the tear down..
How the car currently sits
And new engine arrives..
I thought this was the coolest thing to see.. my engine was literally built about 2 weeks ago
How the new engine currently sits.. just need to bolt the LT's on, clutch, flyhweel, bell housing and it's ready to go back in
More to come.. i've gotta get the cherry picker back from my buddies place and i shall continue with the install. The plan is to go through the top with the LT's bolted to the engine.. so it will be a tight fit! I know it can be done, as my buddy did this exact engine install with the exact LT's on his car.
I will not be swapping valve covers or oil pan on to the new engine. I did this on my OEM engine and i had a pretty bad oil leak, as there was oil all over everything on the original engine (timing cover, alternator, belts, pulleys.. everything). To me its not worth the risk as if you get an oil leak from the oil pan you're going to be either dropping the kmember or pulling the engine to change the gasket. Valve covers.. passenger side is easy, drivers side.. you'll be pulling apart the hole drivers side of the engine bay and taking apart the master cylinder just to get to it. I just don't want to create a head ache for my self again. Plus side is oil changes wont be as much any more with the stock pan lol
