Ok guys I have a lengthy question/issue. So I rebuilt my motor about 4K miles ago. Fresh bore, hone, pistons and rings.. the whole nine yards. I noticed it was lacking power so I did some compression checks. I only did 3 cylinders and they were all relatively low numbers between 65-100 to be exact. I knew at the point something was wrong. The only used thing I have on there is a cam which is in good shape, injectors, and the heads. They are turbo swirl gt40 x aluminum svo heads. I took them off and am getting a valve job done on them in the next couple of days. Upon taking the heads off I noticed there is excessive wear in the cylinder walls of most cylinders. No grooves thankfully. The motor was rebuilt by me about 4 months ago so it’s odd. That’s the back story for you guys, maybe you guys can help answer some questions now. The injectors are also used. From a junkyard but I purchased o rings, needles and baskets for them on summit. Every single one. I have the aero motive fuel pressure regulator and my bars read 55psi. I turners up the pressure pretty high because all Of my spark plugs are turning slightly white on the tips. They are gapped at 55. And the timing is it at 14 degrees. No tunes or anything. Questions
1. Could fuel be hurting my rings or flooding into my oil, diluting it and hurting my cylinders?
2. Does the computer try to adjust fuel and timing automatically? I took the spout connector out when timing*
3. What would cause multiple readings of low compression?
I had to take a plug off of another mustang for the maf sensor I got because I purchased a bbk 24ib injector tuned maf the unit and tube. so I’m hoping it was wired correctly. It ran perfectly just had a lot less power then I expected. No get up at high rpms. The cam is a stage three Crower cam 15513 .512 intake .531 exhaust. Stock pushrod length. Chromoly pushrods.Svo 1.6 roller rockers.
lots of things going on haha, I hope I didn’t lose anybody, this is all very frustrating. I thank you guys so much for any and all help. I basically need to figure out fuel, compression, timing, and if anybody knows the formula to adjust the valves please leave that below because I forgot haha. I believe I did when intake rises do exhaust and when exhaust is at top do intake. No pushrod movement, then 1/4 turn and on to the next. People are getting around 350 whp with my relatively similar setups. Mine doesn’t even feel close. I believe the leaning is happening at high rpms to because it smells somewhat rich at idle. It will sometime die when pushing the clutch in to stop from a roll, and sometimes when the power steering is putting a load on it. I have it idling at about 1000rpms I would like to be around 750 but it dies more frequently. TPS possibly? Sorry for being all over the place there is just a lot of things that are stumping me. Thank you all guys can express my appreciation.
