Cooked my ABA G60. Poor oiling?

[efritsch]

So this is the story, all about how, my life got flipped, turned upside down
And I'd like to take a minute, just sit right there! I'll tell you how I cooked my motor.

I have 7,500km on my motor. Bottom end had an unknown amount of mileage. Head has a fair bit on it I think. I'm not sure at this point which head I used. I have 3.
OBD II block
stock G60 head
3.5bar fpr
Stock injectors
Stage 3 charger, RSR outlet, stock pulley
13lb flywheel

I noticed that my oil light would flicker and sometimes blink at idle when hot. It always went off between 2000 and 2700 rpm when driving.

At this point, I am guessing that something in the head let go from improper oiling. All of a sudden it started blowing blue smoke. Looked like my car was on fire.

I pulled all the plugs and inspected the piston tops with a scope. All appear to be intact. No holes, cracks or damaged that I can see.

Disconnected the super charger piping and the serp belt and drove it around the block. Still blows blue under load and you can smell coolant when you pop the hood. Not much, just a little.

Something makes noise in the engine bay, I thought it was my transmission at first but now, not so sure.

I haven't pulled anything else apart yet. What I'm hoping to do here is get info about what other ABA/G60 owners have done.

I know that the ABA filter flange has a spring/valve in the upper most port and the G60 doesn't. I'm wonder if that could be part of my problem and if anyone has just tapped the hole in the ABA block to accept the G60 flange instead?

Any help or pointers would be great.

Thanks in advance!

did you install the oil squirters for the block?! pretty sure you have to do that for the aba g60.

Stock fuel system? I have a fully built 2.1 aba g60, but I used stock injectors and stock chip and found that my exhaust header was cherry red in matter of mins. My oil light blinks and My rpms don't work, I think I just crossed 2 wires. But running an upgraded super charger with out up graded fuel isn't good. Are u using a stock chip? I used the aba oil flange I think and mine runs good oil pressure at 90 lbs, I never noticed the spring tho. Is it pretty much a stock motor besides the charger?

I have aba block with PG head. I done mine back in 2007. Still running strong with stock pulley. I used OBD-I block, that has forge crank and oil squirts. Also used the aba crank pulley too. My engine had 120 miles on it. I fully built with new rings and and bearings and seals. I put over 80k 5 years. No problem at all. There few things you need to due for proper running. One is fueling, get the right chip and bigger injectors, I used 30# injectors. I had SNS tuning make chip for me. also BBM can make you a chip for this setup too. I did use stock thermostat (87c) and lower thermoswitch for cooling properly. I did add a external oil cooler with thermostat built in, and remove the stock heat exchanger(oil cooler) I also did double head gasket to reduce the compression ratio, I'm closer to 9:1st than 10:1 with stock pistons. The only real problem had was finding the right drive belt.

If you burning alot of oil. Check your charger. It may be worn or you have bad oil seals. Also check your inter-cooler, if oil saturated. Due a compression test that compression is equal. Wost Case you may damaged the ring land on the piston. Also check you have the oil baffle in the cylinder head to reduce excessive oil going to the breather and back into the charger.

The stock aba oil filter housing is best use on the aba block. PG oil filter housing won't fit. I did modify my rear charger bracket to fit on aba block. I grind off the bracket to fit around the oil filter housing and use thin sheet metal as a gasket too. No issue of leaks either too.

Last thing, go put mechanical oil pressure test to read true oil pressure if engine still runs without any abnormal engine noise.

Chc-rado why did you opt to use aba Pulley over g60, we've done pretty much the same everything except mines bored over and a 42 lb sns stg 5, thought that was a smaller pulley

I think I'm using stock injectors (they are green tops) but I do have a 3.5bar FPR and it is chipped, at least according to the P.O. My charger is a stage 3 but its running a stock pulley.

I have since installed a different motor. OBD I ABA and a seriously decked head. 0.030" decked. Makes it an interference motor now. Welded two baffles into the pan. No more oil light though and I'm running 5w30 in it.

Charger only has 15,000km or so on it since I had it rebuilt. It's not the charger. I blew part of the middle ring land off the #3 piston and melted a channel down the side.

The stock aba oil filter housing is best use on the aba block. PG oil filter housing won't fit. I did modify my rear charger bracket to fit on aba block. I grind off the bracket to fit around the oil filter housing and use thin sheet metal as a gasket too. No issue of leaks either too.

That's exactly what I did too. I was just theorizing before.

Last thing, go put mechanical oil pressure test to read true oil pressure if engine still runs without any abnormal engine noise.

I have yet to do that and I really should but at the moment, aside from the banjo bolt for the return line deciding to up and leave the other day, it runs like a champ now.

The G-60 and the ABA crank pulley's are identical as far as I can tell. I think the ABA one is actually lighter.

Because it came with aba block, and it lighter and one piece. I haven't seen negative effect from it.

Question, how that stage-5 chip with 42# injectors. I know I'm max out 30# with stock charger pulley. Last thing I did, I use 50% mix 93 octane and E85 for summer time. Love hat stuff to reducing ping here in hot Atlanta.

[Tim.vw.]

Well if ur asking how is the stage 5 is working, me and bilal are working on it still running rich, headers still glow at idle in matter of mins, but it's half the battle no offense to bbm, I don't know if I'd get the same customer support, this is my 3rd chip from sns, I know there a good company, and I really wanna run their chip. I have a stage 3 rado that runs fine with a tt chip, but it's like comparing apples to oranges. Chip cam exhaust few other things, but nothing like my stage 5,
