    Oil from exhaust after forged rebuild + tune

    Here’s my suggestion, check the intake pipes for oil, especially the one before intercooler at the bottom. If you find oil there, then it’s likely the turbo is leaking oil in the intake. BTW that can also cause smoke at idle and actually drop in oil pressure at idle. If intake is dry, other...

    450 hp set up ?

    I have probe Pistons in my built 7M that I use in my MK3 track car. On 15psi made 327whp and 357ft-lb Many track events after build engine still very strong. BUT I did not drop in the probe Pistons as is! I had to modify the valve relief on the crown, by hand. Take a look at my post on this...

    What did you do to your supra today? Pics

    I don't think these bushings provide the answer. I faced the same problem as I started tracking my car regularly with NASA in HPDE events with ES LFA bushings. The solution I came up with consists of custom made Aluminum rings that fit into the ES bushing after milling the bushing. I ran...

    Strange issues with my 87 turbos cooling system

    ^^^agree. It appears to be minor BHG, but test it to confirm. I picked up a lot from NAPA, but doesn't matter where you get it as long as you get it done. Then as others mentioned don't run it if it tests positive. Sent from my iPhone using Tapatalk

    Bearings knocking, suspected cause excessive oil pressure?

    Have you been monitoring engine oil temperature? If so how high has it gotten on the track? What type oil cooler are you using? Sent from my iPhone using Tapatalk

    #1 plug oil-fouled & can't find the source.

    If it smokes on cold startup then there's a good chance it's a valve guide seal that has popped off the guide. So, do you known if it's been doing that on startups? Sent from my iPhone using Tapatalk

    Probe piston rings no more?

    I agree. No problems with them 5 years dd on 15psi plus multiple HPDE events. For the money, they do a pretty good job. Sent from my iPhone using Tapatalk

    Probe piston rings no more?

    Search "pictures of my rebuild in summer 2009" and you find pictures of Probe pistons with grinding of valve relief edges. Sent from my iPhone using Tapatalk

    smelling coolant from exhaust, what is causing it?

    It's also whenever your engine overheats, say due to bad thermostat or cracked radiator tank, then the oem head gasket is likely to blow. The overheating may doesn't have to be for a long time to takeout the gasket. The MHG will survive overheating as I've experienced when I overheated the...

    Probe piston rings no more?

    Using a Dremel tool. Can send pics in needed, but if you search the forum you'll find info on that. The valve relief leave very thin edges on the crown that can melt if you boost near 20psi. Sent from my iPhone using Tapatalk

    Probe piston rings no more?

    Good to know the status of probe piston rings. Before you drop Probe pistons into the block, check out my postings on grinding down the valve relief edges on the crown. If you already are aware of that step then you're good to go. Sent from my iPhone using Tapatalk

    smelling coolant from exhaust, what is causing it?

    MkiiiAllaDay, If you noticed, all responses you got have an "if the block deck is good" sentence. So you don't have a known course of action because you don't know block deck condition. I am a proponent of MHG only for 7ms. I don't believe in oem head gasket with any type bolts at any torque...

    need help on my my exhaust studs the spin and spin and don't lock

    I do not recommend using a 90 degree adapter. It will be hard to control and my increase the diameter of the hole thus weakening the insert. I learned this the hard way. Best tool to drill is close quarters drill. It's close to 90 degree. I had to cut the bit to fit the drill way in the...

    Probe pistons

    I have 16k miles on Probe pistons. I averaged two NASA events per year since 2010. Also dynoed 327WHP and 357ft-lb on 15psi. So over all, and given the cost, I am pleased with the probe pistons. HOWEVER, do note the following: 1- The machining on the valve reliefs creats extra thin areas...
