Engine blown with only 84000 miles on clock


hp006

Recommended Posts

The engine i have at the moment has currently lost its "cork" which is causing the engine/ radiator to loose water. The garage has quoted £2000 to fix the car this includes

 

Replugging the engine, skimming the pistons etc etc head gasket not sure what else there was. I was just gob smacked at the cost.

 

The car is currently is an na which i can buy the engine for about £500 with 28000 miles on the clock.

 

The garage has quoted about £800 - 900 to simply swap the engines over. Does this sound expensive and how easy is it to just swap the engine yourself at home?

You can do it in a day if you have the tools and a hoist.

Sadly I've done it a few times :(

 

are these `corks` not frost plug type things? Can`t see anything expensive about replacing them??
Depending which one, some core plugs are near impossible to get to with the engine in situ. Also, it sounds like the engine has been damaged due to running after the coolant has escaped.

Yeah i have the hoist, i did not know if it was as simple as unplug/unscrew everything and then drop the new engine in. Does anything have to be retuned etc etc.

 

Apparently when they make the engines there are still holes in the engine and to fill the holes they make a cork from metal and then wack it into the engine. The cork has managed to go onto the inside of the engine, causing it to blow the gasket and needs a lot of work doing, or so they say.

Nope, just swap it over. If you do it carefully you won't even need to regas the AC

That's not right mate. Core plugs don't blow gaskets. Failed core plugs let the coolant escape and driving the car with no coolant is what does the damage.

Also, core plugs are external. They just seal the holes in the block that were there to allow the sand to be removed after the block had been cast.

Have you seen where the plug has entered the engine? if not i would go and have a look first. What the garge is saying sounds a bit suspect to me.

 

as Jake says engine swap is pretty straight forward. and can be easily done in a weekend, or in a day if you are handy with tools.

No, i have not seen anything. I gave it straight to the garage when i thought there was a problem. They did a block test? and it showed straight away the compression was high.

 

So i am thinking of just changing the engine straight over if it is easier and will be cheaper. I have found a yard that has an engine for £500 with 28000 miles on the clock. Does this sound reasonable?

From the gerneral impression it sounds as though it sound not be that hard to take the engine out. Does it make it harder if the car is an auto? or is it easier?

It really does sound to me that the garage is taking you for a ride. If you were to do a pressure test on the cooling system and there was a leak or a gaping hole it would show little to no pressure! not high pressure!

 

Changing the engine will be the better option, and yes £500 is a good price for a low mileage engine.

 

I would say the autobox would be (slightly) easier, as ther is less to disconnect.

16 hours to swap the engine sounds about right, but with the £35 labour charge takes it to £560, not the £800-900 they quoted.

 

I personally would get somone else to look at it just to be sure. As I said, it sounds dubious to me.

 

If the engine is shot then it's really down to you on what you feel is best, I would swap rather than repair but it's wether you want to do the swap yourself, or get them to do it.

The trouble is if a core plug has pooped, then the temp will go high until the temp sensor is no longer in contact with water, and then read normal or low, if you had no water in the engine and continued driving then you are likely to have warped the head, distorted the liners, and there is a possibility that the bearings have started to pic up due to the over heat.

I worked out their labour should only be about £600 but whether they are covering for any mishaps i dont know. They are specialists in Nissan but also do a lot of work on jap cars.

 

I think i will try the swap myself and i'm sure with all the help you guys have given i will be able to call on you to try and help me out of any tight spots that i may get in too.
