Mitsubishi: 4G63T spun bearing?

"Topped up the oil, tried to start, and got lots of valve clatter, the
engine
ran like the timing was way off. There was no audible big end knock. Valve
clatter suggests no or little oil pressure is getting to the lifters."


Your spare lifter has air in it. it will clatter and tick until it get
pumped up.

If you would like, I can point you to vendors who sell the 3rd generation
lifter cheap.

So , Stewart is it a set of Wiesco's on Eagle rods or Ross on Pauter's?

You should talk to Marco over at Magnus in Woodbridge.

Look into the light Stewart, DSMLink and an EVOIII 16G turbo are calling.







 

Not much technical to offer since the motor will need to be opened up. I do
agree with simpleton though, EVO motor. I think I would just rebuild your
current with the good stuff. Actually stock that project car of yours should
scoot...

Take care, L

Its actually a bit slower off the mark with the turbo than with a n/a 4G63
DOHC (first engine I used), though this is in part because its still got the
n/a exhaust system on it, which is 2 1/8" vs 2 1/4" stock turbo. I'll be
replacing it with a 2 1/2" all the way through at the same time I put in the
rear diff and get the AWD working. Its fine up to 5000rpm, then the small
pipes cause to much back pressure.

Once it gets in to 2nd, the turbo torque kicks in, and keeps pulling in 3rd,
4th and 5th. I've had it up to about 180kmh then ran out of road.

Both OEM systems while durable and quiet, are horribly restrictive. On the
old 1G car I went from stock to a David Buschur 3" turbo-back system and
instantly that turbo would make boost like there was no tomorrow. Stewart,
2.5" is a pretty decent compromise between civility and performance. Bigger
is better but more rude, I run nothing but 3" and the drag guys are moving
to 3.5"
What Exhaust components are you using? Manifold, O2 housing etc...

First thing I'd do is check that valve. Watch it with the cover off and see
for sure if is moving. I've lost a rocker and it felt like bad timing,
albeit at a high RPM range. If you put a good/new lifter in there, it will
take a few minutes to pump up. It sounds really bad when you do that.

I doubt you spun a bearing with good oil pressure, so you may be seeing the
valve causing your problems. If you do have a ring problem, pull the plugs
and clean them. I've seen a bad idle with just bad valve seals (oil on
plugs). It takes a bit to burn off that oil. I've had stem seals so bad at
one time, that if you stalled the engine cold, the thing wouldn't start
until you cleaned the plugs.

All standard parts. I could I suppose mill out the exhaust manifold and O2
housing, and put a 3" SS down pipe to a 3" cat, then 2.5" for the rest. It
not and will never be a drag car. (I'm 54 and past that). Mostly I just see
off the local Honda Civic wanna-be's with fart pipes (except for the guy
with the 98 Civic with turbo and NOX ...)

Anyone have some parts lying around?

"Anyone have some parts lying around?"

I sold off that stuff a few years back but allow me to advise you to look at
2G DSM exhaust manifolds and oxygen sensor

EVOIII is better yet but a hard find at the junkyard. On the topic of cheap
OEM Mojo,
2G turbo pistons on your existing rods (w/ the small end reworked) raise
your static compression to 8.5:1

Have fun while you're in there.

Spent half today realigning the cam belt after my mistake trying to turn the
cam : it was 1 or 2 teeth off on the crank gear. Quite a bit less room to
work in the Summit than in an Eclipse, but its spot on now, including the
oil pump.

I have compression, oil presssure under the lifters, spark on all 4 (via
spark gun), fuel on the rail, power on the injector resistors. It should
start, but it won't even fire. I've no reason to believe that the ECU is not
firing the injectors. I've tried some oil in the cylinders, and got a
"sneeze" from the engine.

It too damm hot outside now, so I've cleaned up and repaired to the fridge
for an ale. Any suggestions to get this #@$*! started? More oil in the
cylinders to seal the rings?
