tips on rod bearing repalce

[DSGsupra89]

:1zhelp:Alright I'm pulling out the oil pan becuse I can here a knock going on my car its not loud but im replace it before it starts to damage my crank I'm just wandering is there a tip on getting the oilpan out without droping the tranny really need to know thanks

dropping the front sub frame.....

just pull the engine.

I dont have an engine lift to pull the motor but droping the subframe well held I have an na 89 supra with an turbo motor if that helps

Far easier to just hire a lift and stand and do it that way. Dropping the subframe/pan is a very stupid way to do it. Rod knock, imo, should be FIXED not bodged with a set of new bearings. You want to take the crank out and have it inspected. If you just replace the bearings, you're only going to waste your money in the long run.

i did mine by dropping the sub frame a few inches and lifting the engine a few inches. only took a weekend to do the actual job. and you can inspect the crank in the car, just look for scratches on the surface, and use some plastigauge and a micrometer to check your clearances. if the clearances dont match up, then its time to pull the crank.

^I second that notion. Check clearances for sure.

Actually, I just did this very job about 2 months ago. Mine started knocking and I IMMEDIATELY babied it home and turned it off. If you drove very much at all with it knocking, your chances are slim for this being a success.

I lowered the subframe a bit then raised the motor a bit. I pulled the pan and bearings and found that two of mine were knocking. My crank was good so I put a new set of bearings in.

MANY people will beat you up over trying this (they sure gave me a bunch of crap) beause in MOST cases this will not work. The only way to find out is to inspect your bearings and crank. If the crank is scored or if your rod bearings are beat to all heck. You're done.

This job is fresh in my memory so PM me if you have questions.

Good luck! :icon_bigg

I did not Drive the car I baby it when I first herd the sound it started the same day I posted this thred. The knock strated when I was on my way to work lucky my job is not far from home so I just walk to parts store bought some oil and drove it really slow on the way home.

The knock not very loud anyway too. I know my rod knock you can only here it when its up on rpm around 4,000.

Alright the car came out of surgery the sickniss is gone it all cured thank god thanks guys for all your help the car is running strong. please close tne thread

 

[Rennat]

you should keep this updated with how long your bottom end lasts... im VERY curious to see how long it lasts... and what were your clearances when/if you check them?

 

[CajunKenny]

I agree! ^
I got sooooo beat up for replacing my rod bearings that it would be good to hear about someone else that was successful with this.

Plus there's a little part of me that would feel good about saying "Nah nah nuh boo boo...you were wrong!!!!!" To all those who were not on my thread to help; but, only to cause grief! :evil2:

I'm glad that it has worked out as good for you as it has for me! :icon_bigg

I've got about 3 months of driving and about 2k miles on my rod replacement and she's still tearing up the road! :naughty:

 

[DSGsupra89]

well I did run it really hard last night on the way home I went up to about 110 down the road and then stop don't worry I did this in a clear area and the car hold together its running like a champ but. Wandering what causes the car to burn oil just want to know that too. Also my clearance is fine to only was bear was bad and that was number 6 but I replace them all,

 

[CajunKenny]

A couple things come to mind for burning oil. You could be at the point of a rebuild. If your rings are bad or getting there, it'll burn oil. Another is that your turbo could need rebuilding.

Both instances are common with high mileage or if they haven't been well taken care of.

There are other causes for burning oil; but, these are probably the most common. Someone else might chime in with their thoughts/experiences too.

 

[DSGsupra89]

Alright I got good news car is running like a champ but its not burning oil thank god its burning a little rich on gas but I'm working on it anyway so my car is fine. Its running rich because of the bad acorden hose. Also anyone know how to get code 52 off I took all the a/c off my car and trying to get it off thanks

 

[Mr.PFloyd]

umm code 52 isn't a/c related...

 

[DSGsupra89]
