I blew a turbo a whille back but was still forced to drive the car everyday....

Unfortunately when i removed the turebo to put another stockie one on, i found that it was the front wheel that had gone, and as a result a fair amount of metal had been ground off the wheel and the front housing.....with a few filings found in the intercooler pipes when i took them off....

My concern now is that metal filings have gone through into the cylinders...

My engine blew two weeks after i bought the car and i had it fully rebuild so it now has forgies, honing etc...

I don't know what to do, i think i should be ok as forgies shouldn't develop hot spots and melt as easily as stock pistons... and i can't afford another f-ing rebuild....

Just want to some advice as whether i will be ok or not.

If the filings got into the engine itslef, then any number of things might have happened. It'll act like sandpaper going thru the engine.

Scouring/Scratching of the cylinder walls would be the big one. Especially if the metal was small enough to lodge between the piston and the block.

If you start using a lot of oil/low on compression, then this would be the tell tale sign.

Who knows the damage done.

It would pay to pull all your intake component off eg intercooler, plumbing and even maybe intake manifold off and make sure it is all clean from more metal. I would be reverse cleaning your intercooler to make sure there is nothing left in that, as metal does not do engine internals any good at all. Don't matter if you have forgies or stock pistons, metal will not do them any justice. Not only do you have to worry about your bottom end you have to consider what all those little bit's of metal have done to your valve's and seat's. Only time will tell if it has done any damage, here's hoping it hasn't.

As others have said.

Clean the whole intake system including taking the plenum off just to have a look.

I would also have the head removed and inspected to see if there is any damage before driving more and doing more damage

IMO, you will not be ok.

rb26s get destroyed just by having a tiny bit of ceramic going up back through the exhaust valves.

If there are indeed metal filings in the piping and stuff, it woul dhave undoutably gone into the engine.

drain the oil and run it thorugh some fitler paper and see if you see any grit in there.

Pull plenum off, if there is metel shavings up that far you can guarantee they have entered engine. Dont make the same mistake and continue driving it as it will cause more damage. at the moment you will probably only be looking at a hone, re-ring & head service. leave it to long and it might be a bore and pistons. Kind of a catch 22 situation. good luck, i hope it is the latter.

Its like a compression test - they test the engine and can tell if it is internally damaged or not.

Take it to a good mechanic

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.
