Cross Over Gaskets

Recommended Posts

Hello Forum Members,

I was hoping not to be back so soon. Well after replacing the waterpump and the AC compressor all in 2 weeks a new leak has emerged from the crossover gasket on the front top side. It leaks more after the engine cools of course but i still get some after it sits from driving. I am trying to find out what a fair price would be for this repair. Of course a dealer want $1400. Can anyone come up with a number. I have no clue on this one. Can't even find out how many hours it would take for a labor rate. I am going to replace all 4 gaskets.

Thanks,

Dave

The dealer used to get about $600 to $800 for this job, I would check around. $1400 implies that its going to take 14 hours to do this job at $100 per hour, and I dont think a dealer should take 14 hours to do it, something is wrong, or they have plenty of work and bid you high to see if you'd bite. I did this job on my 96, its all labor, and it helps to have a lift, lots of tight spots. The 4 crossover seals go bad, crack etc. I have a thread someplace. I would say to do it yourself but its a very hard job to do.

Thanks Mike,

Not looking forward to all the tear down. I notice the gaskets are only held in two places were the bolts connect to the block and head leaving a place where it was bound to leak. can't wait to get the new ride in another year.

dave, the crossover connects at 4 places, there are 8 bolts, 2 at each crossover seal. the problem is that the engine conduit, and PRND2 module is in the way along with the throttle body. I removed the electrical conduit that wraps around the front of the engine, PCM and underhood relay center, throttle body, PRND2 module to get at it. If you can afford it, it would be worth $700, parts are about $30. Once you do this job your NS will run cooler and you wont smell any coolant when its hot. Later, I will link you to my thread, I have some good photos.

By the way, its NOT that there are only two bolts at each location, the seals deteriorate, crack and collapse, its the fault of deteriorated seals. You will see when I find my link

Do you think you want to tankle this?

I hope I never have to do them, I had a 96 before and we put in 4 supplement tabs and it stopped the leak, as far as I know it is still good, and it was leaking a bit. not gaurantee that they will work but it is worth a shot

Well is was going to and then I got a hold of my friend mechanic and he said he would do it all on Sunday for $500. Since this is way more than I can handle I gladly offered to help. If you can I would love to see the thread.

Even a blind chicken gets some corn once in a while :D

Thanks Mike

He is doing it tomorrow? For $500, cool, just take your time, mark the PRNDL module carefully if you remove it. Watch how you take the conduit out it is retained in various locations, take you time, DONT break connectors, use a pick. Consider replacing your by pass hose it connects to one of the heater pipes that wraps around back at the top of the crossover near the pump. Take digital photos if you can, it helps.

Ill find my thread

Thanks Mike

Good news is we changed out the 4 gaskets bad news is I still have a small drip from someplace only when it's cold and sits overnight. Not sure where. I will have to take it back to him and see if we can pressure check it cold. Very upsetting :angry: I use to drive it and smell antifreeze even when it was hot but that seams to have gone away. I might be chasing my tail on this one. I haven't had a chance to look real good in the morning for a wet spot

Check the water pump body seal, a leak can appear from there to be coming from the upper crossover seal, also check the bypass hose and purge line for a crack or corrosion
