First at a stoplight on my way to the insurance company it died, started right up and proceeded on, about two hours later of back and forth driving , on my way up a hill it statred to make a weird rattle sound(knocking) my friend assured me it was the motorcycle up the road yet i knew better. i finishe dgetting up this steep hill and yeap ther was a really loud knocking. my friends man came piucked us up and said it sounded like a rod or a lifter. the perrson i bought it from said ther was a new engine put in it. with warranty. is taht transferrable? who does the work, etc etc. and if not what in world is it? please help anyone? ?

Replying to: lauraha (Jun 06, 2009 9:49 am) I'm from england,so unfortunately I am unable to comment on your rights regarding purchase, warranty etc. However I can tell you what happened to my chevvy. the inlet manifold gaskets are a known issue with these engines. mine blew so badly it leaked coolant into one of the cylinders whilst it was running and bent the connecting rod. This made the knocking noise that sounded like your description. I could not tell if it was a lifter or a rod till i took it apart. I removed the heads and turned over the engine by hand and noticed one of the pistons was not rising to the top of the cylinder. I had to remove the engine and replace said rod. Parts cost around $1000 canadian. I presume it is a private purchase, you might be able to appeal to their better nature and get some form of return if you ask, you never know. If not you need a good mechanic, my engine has been fine ever since rebuild, i personally suggest repair rather than secondhand unit - better the devil you know. And it seems to be such a common fault you are likely to be purchasing more trouble. Good luck, hope this is somewhat helpful. I am tracking this thread, if I can be of further help or if you have more info dont hesitate to post

#12 of 20 head gasket by gezzyman Jul 26, 2009 (3:57 pm)
recently started to get antifreeze in one of my ventures cylinders, the van never overheated, found antifreeze in the oil filter (a friend of mine told me the dexcool seperates from the oil so it doesnt get that chocolate milk appearance in the oil pan) Im not sure wether to repair the head gasket or just replace the motor....i hate to replace the gasket only to have the motor blow down the road due to antifreeze in the bearings.it has 125k miles on it and was well taken care of... Is there any way to flush the residual anifreeze out of the motor? any input or advice will GREATLY be appreciated thanks mike

Hello. I live in the phillipines. I own a 2002 venture witha a 3.0 v-6 a/t f.w.d. i'm having a problem buying spare parts from the u.s.a, seems like it's a 3.4 liter v-6 motor over there, my question is did they ever produce the 3.0 v-6 over there and what vehicle did they use the motor on? and what automatic transmission and torque converter,do i have in my venture. on the bright side most other parts are compatible with the U.S version. will be overhauling the motor asap. thank you Replies to this message: 442dude (Sep 04, 2009 7:07 pm) jebernabe (Sep 04, 2009 8:17 pm) 442dude (Sep 05, 2009 6:52 am)
#14 of 20 engine swap from the top by xtremeventures Aug 30, 2009 (11:33 am)
I read a thread online about someone who pulled a 3.4 out of a Venture through the top. I measured it without the exhaust manifolds and there's about an inch on each side. I can lift the engine this close to the edges, but I wonder which approach is best - fastest - safest. Has anyone done a swap this way? Any tips?

Replying to: xtremeventures (Aug 30, 2009 11:33 am) I removed the engine from the top. The head gasket had blown, the antifreeze went into no 5 cyl and bent the rod. I removed the heads and pulled the motor easily without disturbing ac. It was major surgery, parts cost $1000 but the engine is sound now and better the devil you know. Also my engine was filled with antifreeze, it was in the exhaust, oil, bores - everwhere it shouldnt be. I changed the oil and filter twice, once to remove antifreeze, then after it had run for a few hours and hot. That was at 121k and am now at 175k no problems, I even have same oxy sensor. I did strip and clean the engine thoroughly before rebuilding.

Replying to: jebernabe (Aug 28, 2009 10:46 pm) Hello...there was never a US spec Venture with a 3.0L V6 motor - they were all 3.4 L. There was an Oldsmobile version (previous generation minivan) with the 3.8L engine...and the previous version Lumina APV minivan had a 3.1L V6, but again, no 3.0   The only US spec 3.0 V6 that was built up to recently (there's a new 3.0 V6 but its not related) was a 3.0L that was used in the Buick Century and the Olds Ciera as well as a couple other models (Olds Cutlass Calais was another - Buick Somerset, Pontiac Grand AM) , not in any minivans - they stopped building that motor in the mid 80s...it was replaced by the 3.3L which was a bored out version of the 3.0.   The trans for the Venture was a 4T65E and in earlier versions (pre 2000), the 4T65 which still used a vacuum modulator - the "E" stands for electronic shift. Sounds like they might have done things differently for export to the Phillipines... Replies to this message: jebernabe (Sep 04, 2009 8:17 pm) 442dude (Sep 05, 2009 6:52 am)
