Hello Turbobricks' users,
I have a blown head gasket situation on a Volvo 960 / V90.
It is an automatic Inline 6 Cylinder Engine.
I consulted a few auto repair shops but they were asking $3800-$5000 to fix it and one mechanic said it wasn't worth it because it would cost more than the Kelley Blue book value, one other mechanic was afraid to even do a used engine swap fearing not knowing the history of the used engine that would be swapped would come back to haunt him.
I'm not entirely knowledgeable on the functionality of car engines but just computers inside and out so if you need help in that area I could help.
I'm hoping someone that has an automotive knowledge background or experience who could comment on this.
When you have a blown head gasket the extent of damage is unknown unless you take the engine apart.
But let's say I removed the spark plugs and had someone crank the ignition on while I watched to see if any coolant or fluid flew out of the spark plug hole.
I see Cylinder 6 blowing some coolant fluid out but the rest do not.
Does this indicate only Cylinder 6 area has a leak in the head gasket or even a possible Cylinder head warp or crack?
If that's true and Cylinder 1-5 do not have any fluid coming out can you then just put back all the Spark Plugs then disable the Spark Plug Cylinder 6 Ignition Coil so it doesn't fire and just start the engine.
Would this eliminate any exhaust gases from entering the coolant reservoir if it was Cylinder 6 that had the issue with coolant leak?
Would the car operate fine on just 5 cylinders without any issues?
If there are some potential issues doing this please feel free to share as I'm trying to learn.
If Cylinders 1-5 do not have any cracked cylinders, warped cylinders, or apparent head gasket damage in those areas showing good compression would this actually make it possible to have a functional 5 cylinder car with just a horsepower drop?
If so I was also curious if the car can also be made to run on 1, 2, 3, or 4 cylinders using this method if say other cylinders happened to be damaged later on and you just wanted to be able to use the car with just the cylinders unaffected and aren't damaged.
I know these are unusual questions but coming from a computer background I've done tons of bypass methods in that area and was curious if any of what I was suggesting is possible or maybe if anyone actually on Turbobricks might have tried this idea before to get a car to work as a temporary solution until they could do a proper full head gasket on it.
I'm not expecting the car to run like before of course and I may even be okay with it if it can't drive too fast or not be able to drive on the highway and just drive locally at 35mph on roads which still gives this vehicle usefulness for the time being.
Thanks in advance.
