[richmond20657]

Can anyone describe what may cause oil in the hose leading to the intake ? Also have small crack in the radiator on top in the plastic is there any fix to this or do i have to buy a new radiator? Also car seems to run fine but when i nail it the boost gauge will only go to 5-6 lbs don't see a\or hear any leaks any suggestions . Thanks

A bad seal in the turbo could cause it to spray oil into the pipe'n my hoses looked like that before i got a rebuilt turbo, no more evidence of oil spray afterwards.

Crack in the plastic part of the radiator?.... Is it leaking coolant?

Perhaps i am mistaken but i don't recall see'n any plastic on my radiator

radiator is plastic on the top and is barely seeping can't say i have seen a plastic radiator either. I dont have a lot of oil in the intake hoses but it is coated. Wondering if i have some time or will it be going soon. can't get car to boost past 6lbs . changed plugs today and they all looked good but the #5 plug has less wear the insulator under the electrode was still white were the others were brown maybe this cylinder is not firing correctly how do you check the coil packs? thanks

you have a turbo going bad. Get it fixed asap before you mess your engine up BAD. You prolly have alot of miles on that turbo thats in there. Take the pipe off that goes from your air filter to the turbo and you will see the turbo impeller. Take and try to move the impeller up and down and side to side. If it moves at all, you have "shaft play" in your turbo. If the impeller is able to move at all you run a risk of really messing up your turbo, or the impeller coming apart and getting shit into your engine. Get it fixed ASAP and stop driving the car. Oil in your intake lines is a turbo seal, and will always lead to turbo failure.

The crack in the rad can be fixed at a rad. shop. they have the tools to do that kinda work, if not I have a rad. I can sell u off my parts car if you want a cheap OE replacement. Also, the boost not being right is the turbo starting to go. Replace or rebuild your turbo and you will notice a huge difference. also it will take care of the leaking in the intake tubes too. You more than likely have a front seal going bad and allowing shaft play which is effecting your boost. That is where i would start by testing for shaft play. easy and free to do with some hand tools....

Thanks for the info i will check the turbo. The car runs good and makes literally no noise boought the thing for 1900 and figure to have to put some time into it so where can one get new bearings and seals other than the over priced dealer if it needs it?

that is a good place to start. Its a rebuild kit. I paid 900 for the 89 targa turbo that i just got, but the body is a lil rough and needs a paint job. All the things you stated are all wrong with mine too, and that is why I say turbo rebuild. You may need a new BOV too, cause chances are if you spool and get off the throttle you can surge the turbo and almost cause it to turn the wrong way. damaging it. I would reccomend a turbo rebuild and a BOV. that way u dont surge the turbo. Just a few basic ideas of what to do, and how to go about it...
