Have you gotten out to see where its coming from?
I'd guess its your lifters not getting oil. |

i would check where the sound is coming from, but it only does it when its really cold. the engine runs perfect, doesnt blow smoke(unless freezing cold, mostly steam). it wasnt driving for about six months, then i got her up and going did full service and tune, its been running beautiful for the past 6months(no weird sounds). until winter came. i know the thermo is dead(will be flushing her out and putting in new thermo later on today).
think ill take her down to my mechanics and let him have a look. |

I reckon the big end bearing was dying in a motor i've just pulled out, and it made the deep knocking when the front of the motor was higher than the rear, which might have meant less oil for the bearing. If this is true maybe it could be used as a test.
It also did it more so when the motor was cold.
Colder oil doesn't circulate as well and therefore doesn't lubricate as well, so it could be that your problem was there but didn't surface until the current specific circumstances including the atmospheric temperature were reached. Every problem will have a date upon which it was first noticed. |

ok now im 90% sure its the big end bearing, because when the car is parked in the drive way(which is on a hill) the noise is alot worse, and on morings that wernt so cold and the car was started in the drive way the noise was faintly there. thanks for the info relaxed_deplomacy.
ok if it is the bearing then is it worth fixing? and how much would it be? or should i just pull the engine |

I was quoted around $1300-$1400 for a rebuild if i did all the assembly and bearing sizing myself, take off say $100 because my rocker gear was stuffed. I haven't done this before and figure it would be easy to make a mistake first time around. It's better to do a lawnmower first and work your way up. So for me it was an easy decision to fit another motor.
In my first case of a dud motor i fitted an EL motor with 96k on it for $650 with a 6mths warranty plus miscellaneous costs, i used all the original accessories.
This time i'm fitting an AU for $495 with 6mths warranty (maybe got a discount) plus a few hundred more for a full conversion. |

Yeh dont worry about a rebuild unless youre looking at making some serious hp.
Get a motor from the wreckers, much cheaper and you'll probably get $50 back when you take your s**t in, if you tell them what youre up to. |

| im gonna look at doin the rebuild i think, i wanna try and chase 150rwkw-170rwkw. gonna be putting her in to do the diff asap. the the rebuild will come with tax return(expecting a fair bit back). im gonna look into having someone do this for me, or find some that knows what their doing and get them to help me do it(knowledge is the key). all the usual mods will come after or during depending on cash flow. does any one know a rough price for labour on the rebuild? |

It sounds like you're going for a rebuild, but if you change your mind and go for a wrecker motor, i recommend you find the most reputable wrecker you can. It will probably not only be the best, least-problematic experience, but even if it's more expensive (it might not be) it will probably be cheaper in the long run.
Many wreckers fudge kays and offer warranty's that are more of a problem than a solution.
In my search for a decent motor, i first arranged a motor with one particular wrecker, but when i arrived and checked the car that he took the motor out of, it had 40,000 more kays on it than he told me. He tried to manipulate me into taking it, but i walked.
The next one i gave a chance to, told me a good story, but what arrived on the truck was not what was promised. I checked into the engine number with the authorities. He tried to manipulate me but it got returned.
In between these were a number of wreckers that told good story's, but i didn't even give them a chance. |
