Intake antfreeze.leak antfreeze runs out at back of engine

have it replaced. jimmys are bad about this. be glad its not under the motor mounts,those are the fun ones to replace. hope this helps and good luck

Genrally this is cause by the engine oil cooler mounted right above your oil filter, also a intake gasket is plastic on alot of GM vehicals.They will crack from fatigue. Let me know if i helped?

depends on whether its leaking coolant or air, since both run through intake. if leaking coolant, you will see coolant leaking from either the front or rear of the intake itself. it can also leak into the engine, causing coolant to mix with the oil. if its leaking air, usually a small leak will present more when the engine is cold, with rough running or high idle. a large leak will run rough all the time, but should be able to hear air hissing if large enough. a vacuum leak from the intake will sometimes present as a check engine light, with codes p0171 and/or p0172, depending on whether the leak is on one side or both.

This problem appears to be a vacuum leak. Look around the engine for cracked and dry-rotten hoses first and replace as necessary. To check for an intake manifold gasket leak, run propane up and down the rails with the engine running (if you can keep it running...) If you hear the engine flair up in RPM, you've found your leak.

I hope this helps! :)

Is it leaking between wear the head and intake mate together? If so you can try retorqing the bolts and see if it stops other wise you will have to replace the intake gasgets.

check the engine for vacuum leaks at the intake manifold, u can do this with a bottle of propane, spray around the intake when it is rough and see if it smooths out, if it does u found the vacuum leak.

Sorry im late with this,i couldnt seem to log on....The answer to your question is YES,there is a steel line under the intake with a short piece of rubber line attached to it and you can just about see it from the front of the intake with a light,it can leak and cause coolant to run off the back of the engine,The intake gasket set alone is about $40.00 and i dont know about the rubber line,i have seen it physically but havent changed one yet.Note the date of manufactor just incase,i bought an intake set for a 99 and the engine design was changed half way through...its not too hard to pull off the intake and re-install,you will need a 7mm socket for the coil packs,8mm socket for the fuel rail bolts and lower intake bolts and power steering bracket bolts and throttle bracket bolts,10mm socket for the intake bolts and alternator bolts and egr valve,and a large cresant wrench for the exhaust tube thats connected to the egr valve,flat screw driver for the air cleaner...and plenty of extensions with a swivel to be able to get to the back bolts of the intake....just incase you do it yourself this info could make it easier to gather tools.Its about a 3 1\2 to 4 hour job start to finish for the first time doing it,includes cleaning everything..Good luck

My 2000 Boxster developed a pin hole leak in the coolant reserve tank in the rear trunk. The trunk floor is actually raised, which allowed the coolant to go unnoticed, since the carpet never got wet. I would pull back the carpet on the side and see if there is coolant in the trunk area. If so, the plastic reserve tank will run you about $300 for the part. It is a bit of a pain to replace, but something the average home mechanic can do. Only real hassle was the hose clamps in the engine bay were installed before the engine, hence the engine was in the way of the screw head.

You need water and antfreeze half and half 50/50 mixture. If damage to the raditor,it will leak outside. If damage to the engine it will leak either outside or inside into the oil,and the engine is usually badly damaged. I hope you replaced the water with the antfreeze in time.    

I know this darn hose, u have to pull the intake to replace it, we used the factory hose but you can use any type of water/coolant rated hose in that size.
