Vortec 4.3L V-6 -- Opinions Wanted.

How come you and others call this engine a 90 degree engine when the manual says it's a straight 6 cylinder?

The above posts refer to the V-6 4300 cc Vortec engine. Your Bravada has the I-6 4200 Vortec.

Not all "Vortecs" are the same.

All I can tell the negative complainers is there are 2 -4.3s one has a bala ncing shaft in the oil valley I have had two fleet trucks with that one in it one throttle body vortec in a 94 heavy half ton and one 2500 express va n with a port injected vortec 1998 both are still on the road they both go slow up steep hills they have incre dible grunting torque One thing I know about engines is engine failure is quite often operator er ror I'm never in a hurry I can roll down a hill 115 mph and baby it up the next one only to down shift still doing 55 at the top of the next one how y ou drive it is how it will serve you it tends to shift down into 2nd early if you have your foot in the throttle too far get over it drive it don't wr eck it those of you blowing these engines .... Go get the 500 horse engine and belly up to the table instead of repetitively replacing engines...(mean s someone doesn't get what this engine I for ... I have had 8000 pounds in my van and never had to creep slower than 35 if you want a race truck pay t he $60,000 bucks and belly up to the table to keep it trucking , in my opin ion the 4.3 is one of the best Chevy engines ever developed or even the be st.

I dont seem to mind the 4.3 v6.. i believe i had a 1996 s10 a few years bac k didnt have to many problems withvit.. and the i bought a 2000 gmc sonoma. .. well i decided to do some work on it because i figured it would be bette r on gas with an upgrade.. i upgraded brakes system all 4 brakes new .. an d the upgraded spider injector and some suspension.. after a few weeks foin g the work myself and learningnhow to do the wptk on this enegine for the f irst time.. i dont mind the simplicity of taking this apart.. and its cheap parts make it easy to rebuild..

I found the abs system is complete bullshit ccuz wtf i cant do my wjole bra ke system without a scan tool .. thats complete s*it.. but if it ever comes down to it i wouod love to swap out engine eventually. Even though the son oma is a tiny truck i enjoy it. It does what i need ... and since i did the upgrades i have actually gained some milage difference then when i first g ot it

I have a 1998 Oldsmobile Bravada with a 4.3 Dieter V6 that is smooth and ru ns great very strong launch is the line very strongly I've owned this vehic le we're not quite a year yet and bought it second-hand with a hundred and

I'm a little puzzled by Scot's experience. I own a 4.3L 2009 Silverado 1500 and have had no problems since new, other than a factory recall for leakin g intake gaskets. I even towed a car trailer with a 3400 pound vehicle aboa rd--effectively maxxing out the trucks load limit across the country with n o problem. Granted I took it easy and the motor used a little oil, but no p roblems. Maybe GM improved later versions. I will say the idiot who designe d the side mounted oil drain plug ought to be forced to get oil splashed in HIS face when he removes the drain plug. Stupid moronic place to put a plu g.

I own a 1996 Vin X S10 and whole I had tranny problems because I towed heav y trailers with a stick automatic, the only real engine problem I ever had was a intake manifold gallery break and take out a crankshaft bearing. I re built the motor (bored over. 030, changed the lifters and pushrods and rock er arms, fla flattop Pistons and zero decked the engine and did a valve job on the heads with dial rate valves).I also rebuilt the tranny to take the increased torque of the motor. And ended up replacing an axle and exhaust. Now it is a street thug that gets exceptional MPG. The 4.3 vortec is a grea t motor that has very high potential... After you liberate it from the manu facturer restrictions and the EPA.

wow I myself have owned 6 different vehicles with the same and i "quote bastard engine" I have even put a pro-charger on one.... Its amazing how such a s***ty engine as this article describes could yet not ever give me an issue that couldnt be corrected... So experiences are just like opinions everyone has one. also the Inline 5 that they used in the colorado is a real piece of crap for sure!!!!! I have a canyon and it gets horrible gas and couldnt get out of its own way if u needed it to!!!!! WAY TO GO GM way to mess up the wet dream.....

I've owed/own 3 different S10s all three have over 300,000 miles and that heart a 4.3 v6 with that being said your opinion is ONLY that...an opinion!

My 94 S10 Blazer is fine. 4.3L W CPI, has almost 300,000 miles on it, (less than an oil change away...) Runs good, Looks good (recently painted....) I got it as a clean 1 owner 18years ago when it had 127,000 on it. It has been a solid reliable daily driver all it's life, and still has a long way to go.....

Sorry pal but you don't know what you're talking about. 233k on my 97 astro and doesn't use a drop of oil. Runs absolutely great. L35 4.3 vortec and again, you're absolutely wrong on every level.
