Engine problem , would appreciate your input

Hey guys ,

New to this forum and have been a typhoon owner for a few weeks. Love the truck...

Tonight I was driving it with a friend giving it about 30% throttle. Doing a couple of passes the turbo stopped spooling and the motor became really sluggish , assuming it's due to the turbo not boosting.

The previous owner did a little jerry rigging with an aftermarket intake but other wise it's a stock motor.

I just went down stairs to listen for any type of rod knock , motor sounds clean but hesitates to go past three thousand rpm's with half throttle . No knock , motor revs up fine with no abnormal sounds. The oil pressure is over the half way mark before three thousand rpm's.

What sucks is having to go to bed thinking about this. In the morning I plan on removing the intake to see if the turbo spins by hand.

I'm thinking ( hopefully ) that a line to the turbo came off or something of that nature.

Can you guys chime in with things I should look for that are prone to coming undone under boost.

Thanks again

Do you still have the crossover tube with the stock airbox? Make sure that none of the pieces broke off and got sucked into your turbo. Do you still have all of your stock vacuum lines? You may want to start there. Probably not the problem, but it is a simple place to begin...

x2 pop the hood look at loose stuff, otherwise take the intake off and check if the turbo spins freely

Are you getting tach flutter? Being a new owner, I would do a full tune up and invest in a scan tool before doing anymore boost runs. Even if it sound fine, the truck could be inaudibly killing itself with detonation. You don't want to join the exclusive group (but note rare) of new syty owners who blew their engine within the first month of ownership.

thanks for all the swift responses.

I will take some pictures later on today of the engine bay.

A few of my friends that are turbo specialists down here said the waste gate might be stuck open or the turbo is gone.

I turned the engine on this morning , no smoke and the oil pressure is still over the hald way mark. The vacum is at -10 but it will not boost. Test drove it down the street but it won't go over three thousand rpm's and feels like a NA motor with low compression.

Even if the wastegate were stuck open you could get over 3k rpm. I'm with the other guys in thinking a fuel pressure problem, or the turbo having gone south. If high mileage, jumped a couple of teeth on the timing chain?

Re: Engine problem , would appreciate your input

so i checked the intake piping from the turbo while the truck is on and it's pressurizing.
is it true if the plugs are gone and fouled out it can stop the turbo from creating boost?

planning on jacking the truck up to take a look at the rod from the waste gate , I need to remove the c clip and see if the rod has movement .
question is , where is the wastegate located exactly on these trucks?

thanks a lot for all the input you guys have contributed this far. much appreciated!

I would guess that a vac line blew off somewhere... -10 psi of vac is way off with a stock motor. It should be 18-22hg if vac. Start checking for a vac line off somewhere. Also if the wastegate is stuck open you should still be able to build boost.

Re: Engine problem , would appreciate your input

thanks .

can you point me in any particular area to look ? maybe certain vacum lines that are prone to pop off?

Any of them will become dry and brittle.... especially those little hard plastic pieces. Start at the vacuum ports on the manifold (you'll see vac lines attached to them)... follow them clear to the end of where they go.. you'll find it, but the leak could be anyplace as they're not prone to cracking at just one location or area.

Buy the silicon vac line kit from Adam and replace so you know its good to go and out of question.

x2. I would just go ahead and change every vacuum line in there. Buy the kit. It makes things simple and may just fix your problem. You are in there anyway poking around, so you might as well get familiar with it all and change the lines.

Order one of Adam's kits. This will give you a few days to "cool off" and not hate the truck so much. Then take down time and just do a little reading/searching here. We all know that these things aren't the easiest beast to tame, but believe it or not, they do run great once you get a slight handle on them.

The kit is VERY easy to install and comes with excellent directions. You sound like you know what you're doing, you just need to learn some syty patience, young Padawan. Good luck:tup:

Re: Engine problem , would appreciate your input

the kit sounds like a plan ! I appreciate that...

I want to check the waste gate and remove the c clip holding the rod in place to see if it has the proper movement , question is. How hard is it to get to the waste gate ?

is it visible and easy to get to ?
