hey guys, having coolant issues with my 95 max, coolant seems to be dissapearing I found out tonight that theres oil in my spark plug tubes(only 2 of them in the rear). I checked the oil and its not mixing together. would the 2 cylinders loading up on oil having anything to do with coolant consumption?

 

The cylinders aren't 'loading up on oil', your plug tube seals are leaking. Replace them and valve cover gaskets, as they're likely leaking as well by now.

Disappearing to where? Have you checked for leaks? Do a pressure test of the cooling system, see if it's leaking. It's likely a bad water pump seal or a cracked rad.

 

when you take off your radiator cap(after car has been running a while, then shut off) is there steam or alot of pressure when takeing it off. you could have circulation problems in your system that is just making it steam up and dissapear on you. i know i had a problem like this with my car. when coolant breaks down over time you can get corrosion buildup in your system which can impede on the flow of the antifreeze. all i did is go to a valvoline and have them do a complete flush of the system. Problem Solved. when was the last time you ever flushed your coolant if at all? No leaks?

 

How many miles are on your max? Check for leaks.. see if there's any residue around the radiator, hoses, pump. The OEM radiators on these cars are only good for around 150k before the plastic starts becoming brittle and cracking.

 

^^ yup, same thing happened to me. I just change my radiator, it was cracking at the top

 

I will pressure check it and go from there thanks guys

 

its the head gaskets, coolant and the oil are mixed making the famous milkshake. any tips?

 

Where is it looking like a milkshake, in the rad or the oil? If the oil, filler cap or on the dipstick?

Have you done a compression test or checked for exhaust gases in the coolant?

 

its on the dipstick and I started to pull the valve covers and such off and its all over the inside of the motor

 

Well your tips are to either replace the headgaskets, or swap the motor. Though I wonder how the hell you managed to blow a headgasket on a VQ30...

 

well I dont believe it either but it has happen, so I take this time to replace alot of timing issues and guides and such. I'm still laughing at my local dealer who wanted 5500 to do the job. It is a pain in the *** but its do able

 

anybody know where I can find online 13091-31U26 and the gasket 13079-31U00???

 

Did you google the part numbers, or google 'nissan parts'?

13091-31U26, $65.88
13079-31U00, $5.69

Give Dave B a call, you'll likely get it cheaper and faster from him.

 

head gaskets are done along with a new water pump and new timing components, she runs great. thanks for the help guys
