I've searched for coolant leak but didn't come up with anything related. I removed the turbo's since it looked like the leak was coming from behind that area, took these pics just above the turbo area.. any ideas?

The pics are a little repetitive as I was taking them from above the car just randomly shooting and hoping to get some good shots

Thanks in advance

Yep, replace both of the turbo coolant lines.

Its got to be either the soft coolant hoses, or one of the banjo fittings on the turbo chra. If you have the turbos off replace everything. You can't get to the inside turbo coolant banjo bolts with them on the car as they are wedged up against the lower intake manifold.

Also check the hose that goes from the rear iron housing to the throtte body. If you have coolant pooling under the upper intake manifold that may be the leak.

Okay I'm not sure if I'm understanding completely but if you guys are referring to any parts of the turbo causing the leak, that isn't the case as this all happened after the turbos were taken off. I cleaned up the mess that was made before the turbos were taken off, plugged up the two coolant hose outlets and filled the coolant back up and this mess was the result. It looks like it's actually coming from in between the LIM and the block? is that possible? or am I missing something..

thanks

It could be possible that your motor was built with TurboII rotor housings instead of FD rotor housings. TII housings have a water passage that goes from the rotor housing through the lower intake manifold to the turbo.

Check out this video -

Pineapple Racing shows you how to install a freeze plug in that hole to seal it up. It MAY not be the case, but if you're that far in there it might be worth pulling the lower intake manifold and knowing FOR SURE. It actually looks like the coolant is seeping from between the motor and LIM, so that's a possibility.

^ that actually may be the case. I randomly stuck my camera down there for a minute and recorded a small video of the coolant seeping out from between the motor and LIM so I'm going to have to just pull it off and take a better look.. would the UIM/LIM be incredibly hard to pull off for someone that's never done it before?

Thanks for the video Dale.

If you've never even pulled the upper intake manifold, you're in for some work .

I have a writeup on ClubRX.org on how to pull the upper intake manifold. The lower requires the fuel rails to be removed or at least unbolted, you have to remove the air control valve and some of the rat's nest. It's pretty messy. You might be able to unbolt the lower intake manifold with that stuff still attached and peek in between to see if that's really the case.

Regardless, if that is the case, it'll be a pretty big job.

^ Thanks Dale, I went through your UIM page before I went a-hackin away into the unknown. Thanks to Rotary Experiment Seven as well for giving me pointers before I went diving in.

I managed to pull the UIM/LIM off, and it looks like you're right, Dale. I've posted pictures for you guys to confirm but that looks like it may very well be the case. It looks like there is some brown crap that I can't really make up in those holes. Aside from that it doesn't look like there was any effort to plug up the wholes. Some brown stuff and the gasket, that was about it.

Question; are there any downsides to TII housings, other than these unnecessary holes and my need to plug them?

PS. would anyone be able to tell if the motor was ported by these pics? :x?

Looks like Slimer went through you engine.

Yeah, that's some green damn coolant!

Sludge will accumulate there - it's a dead spot in the cooling system, so some goo is not out of the ordinary.

As far as I know, TurboII rotor housings are damn near the same. I think the FD housings had a slightly different coating on the surface when new - that's all I can think of, besides the cooling passages.

I'd get those freeze plugs from Pineapple and install them just like in the video - that will permanently solve that problem. Also, if you had a paper lower intake manifold gasket, make sure to replace it with a newer metal gasket. Heck, I'd almost go ahead and replace the gasket anyhow considering it's been serving as a water dam up until now .

I hate to add to your bill, but looking at those oil metering injectors and rigid looking vacuum hoses, you should consider doing the 'hose job' and replacing the vacuum hoses, and also consider changing that FPD. These nooks and crannys are a PITA once the engine is in.

Your pics look like 13B-rew vs Predator....

haha, actually they do now that you mention it. The reason the coolant is so green and glowy is because I added some UV reactive liquid (like maybe 5 drops) in an attempt to locate the leak since I had basically 90% water before and couldn't make it out.

I'm cleaning up the mess now. Ordered some freeze plugs from pineapple (thanks for that Dale, I was starting to worry about where to find them), after I debated whether or not to simply JB weld a quarter in there :] This might be cleaner.. however if this pops out, I'll probably stick that quarter in. I'm giving Ray a call tomorrow to pick up a few gaskets as well, the current ones are metal but they're full of slimy slug now.

Dave, thanks for the tip, I'll look into the hoses. Though there aren't very many on the engine as it has been converted to non-seq (which made this job a hell of a lot easier), and a lot of the fuel lines are braided SS as well. I'll look into replacing the FPD as well.

Now that I think about it, this may have been why I had so much white smoke on startup. The coolant easily could of seeped out of these holes and into the port, when the car was sitting since I would continuously add water but couldn't under stand why so little water was actually hitting the ground. Perhaps my coolant seals aren't bad after all! `crosses fingers` does this seem plausible at all?

I will update once I have everything reinstalled and, hopefully, fixed.


edit: any opinions on the Rotary Performance oil metering lines?

Glad you're getting things solved.

IMHO, the stainless braided lines are way overkill. You can buy many sets of stock lines for the price, and the stockers last a VERY long time before they get brittle. Not to mention stainless braid rubs through EVERYTHING - if it isn't carefully routed and sheathed, it will rub through hoses, wiring harnesses, you name it.
