So, From everyones experience or just hearsay, how much more difficult is it to do the head gaskets with secondary air than not. I'm asking because I ordered the gaskets from AB and want to put them on this coming weekend (my father and I), but i have heard it is a LOT harder with the secondary air. My gaskets aren't leaking yet, no coolent smell coming from the truck, no thing like that, just want to replace all of the gaskets and do all of the preventive maintenance before hand. What i thought to be leaking just turned out to be the A/C unit dripping down after the truck was shut off.. stupid me right?? anyways, is there a way to re-route that tube so it doesn't fall straight onto the drive shaft.. that can't be healthy day after day for the drive shaft...

Anyways, any input would be much appreciated!!

Thanks everyone!!

They are not that much harder to do. Do you have a shop manual, you'll want one.
As for parts, you will also need new head bolts, new t/stat and 8 mm plug wires.
That being said, have the gaskets been replace before, and why are you wanting to mess with something that is not acting up?
Also doing it over a weekend, especially with your mileage may not work cause you will want to have a machine shop inspect your heads for warpage and resurface if necessary.

 

Well, it doesn't have to be done over the weekend.. I don't know if they have ever been replaced to tell you the truth. They aren't leaking. I got the set of bolts and a new t/stat already. The plugs and wires were just replaced not more than 2 months ago. Should I just wait for it to start acting up or while I have the time now, just go ahead and do it? I guess the main reason doing it right now is a good option for me is because I have SOME down time at work, I generally only work about 3 months a year, give or take a month to a month and a half... Its going to be getting busy pretty soon and I would hate for something to go wrong when its busy at work... I have other means of transportation, BUT, I don't want the disco to have to sit until I have the time to fix it ya know. I am also going to replace the O2 sensors, i'm getting codes P0130 and P0133.. I know its time to replace those things so that is on the list for this weekend as well..

Hey, do you know if that will cause a rough idle? Do bad O2 sensors cause a rough idle? Just wondering, its not often at all, but every once and a while and usually after I fill up all the way with gas for about the first 50 miles, I have a rough Idle....

Any thoughts on that...

Thanks for the insight.

And yes, i do have the shop manual!

Thank you,

 

Normally the 02's won't effect the engine to the point of causing a rough idle.
Who's wires and plugs did you install and how long has it been running rough?

 

Had a similar problem with a rough idle.

While you're in there, do a Seafoam induction cleaning (see Disco Mike's instructions) clean the throttle body and clean the IAC (the latter is is what totally fixed my rough idle).

 

STI wires and Bosch Plugs. I haven't done the sea foam. I was going to do it, but I just changed the oil right before I bought the sea foam and from my understanding, you have to change the oil right after the sea foam cleaning. If that is the case though, I will re-change the oil and do the sea foam and t/body cleaning this weekend and see if that will take care of the problem as well as the IAC cleaning. It has been running rough for about a month or so now... and as mentioned, as soon as i picked it up, I did the oil changed and changed all of the fluids really so I didn't want to re-do the oil changed, but if thats what it will take to get rid of the rough idle, i'm down to do it!

Thanks for the info as always and any more pointers you can send my way, please do.

Best Regards,

 

Yes shane if the o2 sensors are bad enough they will cause a rough idle ive had it happen to me i switched them out and it went away

 

awesome, its on my to-do list for sure... VERY SOON i might add!!

Thanks again for the response... I am going to clean out the IAC today if the weather permits though, hoping that will do the trick in the mean time.. we'll see, I will let you all know what happens of coarse.

Until then my friends....

Take er easy like Sunday morning,

 

Shane,

I wouldn't even consider messing with headgaskets unless they are leaking or blown. They may never go and it's not really a preventive maintenance procedure. O2 Sensor CAN cause a rough idle, but I wouldn't replace those either until you can definitively rule it out. I DO NOT know which scanner will allow you to watch the 02 sensors work while the truck is running, but that's really what you want to do...they're a lot of money...and if it doesn't solve it, you may have well just stuck those bucks in an envelope and sent it to me.

Follow Mike's instructions on a manifold cleaning and go that direction. Always go simple first and work towards the complex. I'm brand new to Rovers, but I've learned years that basic, simple failures happen 10 or 12 times to every 1 "oh ****, it's bad" situation on most things mechanical. Probably even more than that! It also helps you sleep at night not worrying about a blown motor when it's just muffler bearings or the afterburner "O" ring timer thingy.
