Keep getting air in the coolant system. Having intermittent starting issues.
Ok guys. I’ve been dealing with issues for a long time now. I keep having intermittent no start issues. I always have fuel pressure when it happens. I’ve also noticed my car smokes just a little at start up until it warms up. Looks like white/coolant smoke. I also keep getting air in the coolant system because my heat quit working and I bled it the Billman way and got hot heat again. Today I noticed it’s not hot again once it even gets warm it gets cold at idle. I seem to be losing coolant also.
Before I knew the coolant thing for a fact, I took it to my friends shop to check it out this last time it wouldn’t start. He put a new battery in and a crank position sensor and it fired up. I went to pick it up and right before I got there they figured out it wasn’t starting again. We kept trying to start it, we could hear it trying to fire up a little, and it fired up finally. It’s ran since for the past few days but now it’s hard to start. I have to give it throttle to keep it from dying to get it to start.
I’ve also gotten codes P0300, P0301, P0302, P0303 and P0304 before but not now. I don’t always get all the cylinders but I’ve gotten them all at different times. I also got the air pump code pending once(can’t remember the code number). I only get codes at start up. I clear the code and drive and I never get it when driving. The car runs great when driving it’s only a starting issue.
Some info about my engine. It’s a sleeved and stroked F24 InlinePro 9.0:1 motor with a stage 1 rebuilt head. I have about 5000 miles on the engine. So it’s fullly rebuilt and assembled by InlinePro with new oil pump and InlinePro tensioner and all new gaskets. Only other engine mods are Hondata intake gasket, K&N FIPK intake, Invidia test pipe, AEM fuel rail and regulator, Walbro fuel pump, mishimoto thermastat, new coil packs and plugs and I think that’s it engine wise. I also have an AEM Wideband. I’ve never overheated it or ran lean. The air/fuel has always been perfect.
I checked the compression the first time I had this issue and the numbers were almost exactly the same(within 1-2 psi of each other). The plugs were also all clean but I’m going to check both of these again. This happened the first time and it started running again for seemingly no reason. It ran for 4 months with no problems and started again. I will say this. Since I got the InlinePro engine in it has always acted weird at start up when cold. You crank it and the engine stumbles for just a second and then catches itself and idles right. For a second it sounds like it’s going to bog out.
My symptoms seem like a head gasket as far as the coolant part, right? I’ve also heard bad things about the Hondata gasket lately. Is it possible it could cause this? I know there’s coolant that runs through the intake manifold. Any help is appreciated. I’ve been banging my head against the wall since I got this engine built. Thanks guys.

What’s weird is it’s a freshly built engine (started having this issue after 2000 miles) with a new OEM head gasket. What could cause it to fail prematurely?

I’ll have to ask InlinePro but I assume they used OEM. I doubt they would use something else. I’m actually willing to bet it was the torquing they got wrong. When I got the engine back it was fully assembled. At first start up it was leaking oil real bad from the oil pan so we had to shut it off immediately and redo the Honda bond on it. I figure these guys build these engine so much they never make mistakes but I guess anyone can. Maybe the new guy assembled my engine. Lol

If it is anything other than 87mm, it is something other than OEM for sure, but they may have used an aftermarket gasket even if it was STD bore. May be a good idea to go over the paperwork to identify the parts used.
