Question about Cars & Trucks

2 Answers

I have a 2002 Nissan Altima with a blown head. Constantly losing coolant and tries to run hot every other day, white steam from the tailpipe and it won't accelerate properly. I don't have the money now to repair the head so I was wondering if anyone had used blue devil sealant for this problem and how it worked on a 02 Altima. I read some good reviews, but none for my vehicle. My mechanic said it's use at your own risk because it can cause clogging of other things like the radiator and heater coil. Please help! Thanx

Take the head off yourself to save money.

No sealant with work as this, It is an internal engine problem.

SOURCE: head gasket sealant

As a A S E Certified Tech I Do NOT RECOMEND ANY "QUICK FIX" ADDITIVES Especialy for such a Critical Engine Component

More Costly but Also More effective is to Tear down Engine and Replace Head Gasket as You may have A Cracked Head Or Block That NO ADDITIVE will TRUELY REPAIR PROPERLY

SOURCE: High Idle

I have a 2001 Nissan Altima and mine did the same thing. We replaced the intake gasket. It costs around $5.50, but it requires several different kinds of tools. We spent over $100 in special sockets, etc. But once you replace that gasket, it will idle better.

SOURCE: 2002 nissan altima + black smoke coming out of tailpipe.

To begin with, check for fuel in engine oil and do a compression test. If fuel system is not functioning properly (running rich) that will point you in one direction (temp sender, pressure regulator , map or airflow sensor etc) If compression is low, you may have internal engine problem (burned piston, broken ring, or combination of fuel problem causing gas washed cylinders)

Check your coolant system to see if you are losing coolant as well. The symptoms you describe are indicative of a blown head gasket or a cracked cylinder wall. A compression check may be a some assistance as well.

2002 pathfinder when it sits for a long period of time n i start it it blows alot of white smoke through exhaust other than that it runs fine


White exhaust smoke usually comes from coolant in the cylinders, indicating a cracked head or blown head gasket. The best test is to pressurize the cooling system, then remove the sparkplugs and look for moisture in the cylinders. Turning the engine over with the plugs out will spray a mist from any cylinder with coolant in it.

CAR OVER HEATS AND APPEARS TO BE LOSING COOLANT OUT EXHAUST PIPE..


If, in fact, you're loosing coolant thru the tailpipe, then I'd expect you have either a blown head gasket or a cracked head.

Check around with friends, relatives, neighbors, etc. and try to get a consensus on a good local mechanic, then go to him for diagnosis.

White smoke coming from tailpipe? Slight knocking noise. 99 Camry.


White smoke or steam? Smoke is oil buring and steam is coolant steaming. If this is steam, you have a blown head gasket...if oil, it could be either a oil ring problem or a valve seal problem.

White smoke out the exhaust


Sounds like antifreeze, possibly a blown or leaking head gasket. Check your engine oil dipstick to verify the oil is not creamy white indicating head gasket. Hope this helps

Car using a lot of oil and going out of tailpipe


Back to what I said before, only perhaps it didn't get really hot. Only two major causes of oil burning. 1. rings and cylinder walls are worn or 2. bearings are a bit out of clearance and throwing more oil on the cylinder walls than the oil rings can deal with. Other reason should have been taken care of when head was done: valve guides & seals. You can still read good compression with certain conditions. a more accurate test is a cylinder leakdown test. On another idea, if one cylinder was being washed down by coolant, it may have unseated the rings. sometimes they recover from this, sometimes not (likely in the cylinder with warped valves. Check that plug for oil fouling...could be where miss is.

Blown head gasket


Look the engine over and see if you can find any external leaks, change the thermostat and make sure that fan(s) are operating.
Check the oil for water...loosing that much, it has to show up somewhere. Blown headgasket usually puts oil in coolant or coolant in oil, causes an external leak from between head and block or goes out through the tailpipe as steam.
look carefully and you will find your problem!!
